Help:Image maps

This article provides access to an image map editor and the step by step instructions for creating multiple links within a single image.

The ImageMap extension to the MediaWiki software allows you to insert images with clickable links into articles in the wiki. With the ImageMap extension, you can make an entire image serve as a link to a different article, specify a particular area within the image, or you can select multiple areas within that image to link to different articles. The ImageMap extension is a powerful and flexible tool, but because it is coded in HTML and defines regions via coordinates, many users may find it difficult to use at first. This guide will show you the easiest way to use the ImageMap extension to use an image to link to another article.


 * Note:It is not necessary to use an image map to add a link to an entire image, this can be done by adding an image link.

'' Are you tired of going back and forth between the page you are editing and the image map template just to adjust the image size? ''

'' Do you want to avoid making multiple copies of the same template in order to use the same image map on different pages with different image sizes? ''


 * If so, check out the new Trick of the trade in this help article for the solution.

1. Upload your image

 * Upload into FamilySearch Wiki the image you want to make into an image map.

2. Copy the URL for the image

 * Find the file for the approved image that is now within this Research Wiki by searching the image name or by using ListFiles to check recently uploaded files.
 * Right click on the image and choose Copy image URL.
 * Note do not copy the URL from the browser window, it will not work.

3. Open the Image Map Editor
NOTE: The link to the previous Image Map Editor is currently unavailable due to User account expired. The following replacement is is an alternative editor. These directions have been updated to reflect the new editor. Please report any issues or suggestions for other editor options that could also be included here.
 * Open Editor

4. Load image into editor

 * Paste the URL (as obtained in Step 2) into "image on the Internet" box of the editor.
 * Click "accept" (or use the check mark).
 * The image will show up in the image box immediately below.
 * If image does not display, you have a problem with the URL and should return to Step 2.

5. Open an area section and select the desired shape

 * In the Image Map Area of the editor click on the plus (+) icon to open a new shape section.
 * Note: The minus (-) icon is used to delete the currently selected section (a black dot in the circle to the left of the shape section shows the current selection).
 * Select the area type you wish to create: Rectangle, Circle or Polygon.
 * Most of the time you will probably be using Polygon as most images you will be outlining do not have regular shapes.

Circles and Rectangles

 * Go back up to the image box and left click near the desired area in the image.
 * Drag the cursor away from the initial point (for circles and rectangles) to enlarge the shape.
 * Note: Hold down the shift key to change a rectangle into a square.
 * Left click - HOLD inside the shape to move it to the proper location.
 * Move the cursor over the shape boundary until arrows appear then left click - HOLD to resize the shape to cover the desired area. Repeat as necessary.
 * Note: For the circles and rectangles the arrows will appear on the top, bottom, and sides.
 * Note: You could also type number changes directly into the coordinates box if desired.

Polygons

 * The creation of the polygons is a little more complicated.
 * Left click on the starting point of the area to be selected.
 * Click on the various parts of the image you want to be part of the polygon's area.
 * As you progress along the borders, the area will become shaded.
 * To "close" the polygon hold down the shift' key while marking the second to last point at which time the border will connect back to the starting point.
 * Note: Polygons cannot be resized (they must be redrawn). Select the appropriate shape section by clicking in the circle to the left of the shape selection box (black dot will move there).
 * Move the cursor to the new start point on the image and left click once the cursor cross hairs are visible. This will erase the old polygon when the new one is started.

7. Install links and title

 * Put the link to the article in the Wiki for the area you are outlining into the "Href:" box for the current shape section.
 * Or use the URL for a site outside of the wiki.
 * Next, enter the title (tool tip description) in the "Alt:" box. This will display the tool tip that will appear as the cursor is hovered over that specific area of the image.
 * If you only have one area to install, click "Enter" after you have type in both the "Href:" and "Alt:" boxes, otherwise they will be added when you click on the + button to add the next area.

8. Check the coordinates in the ImageMap box

 * After you have finished with the first area, go down to the ImageMap extension code box and you will see the coordinates of the area you just outlined.
 * Notice that the link and its name is between the set of double brackets . If you don't see anything between the   go back to the "Href:" and "Alt:" boxes and type in the name and tool tip and hit your Enter key.
 * You will also notice that the area you have outlined is now shaded so you can see what areas have already been covered.

9. Create the next clickable area

 * To create the next clickable area on your image, click on the plus (+) icon to open a new section.
 * Enter the next link and title as was done above.
 * Repeat the above procedures (5 - 8) until all the desired areas have be marked.
 * Note: For overlapping image map areas, the first drawn area (the lowest) will take precedence over any click-able areas drawn above it.
 * When you have finished all the areas you want to outline, go to ImageMap extension code again and copy (Cntl C) all the code in the box including

10. Create imagemap template

 * Open a new browser tab (if preferred) and type into the search box a name for the image map template you want to create, for example, Template:Name of Your Image Map.
 * If the name you selected is not being used it will appear as a red link. If it is not a red link than you should repeat the procedure until a unique name is identified.
 * Click on the red link and then edit page to create your template.


 * Paste in coding you copied from ImageMap extension into Wikitext editor (not the Rich Editor).


 * IMPORTANT Using the Wikitext editor install this code  __ NORICHEDITOR __ at the top of the page.  This will prevent anyone from opening the file with the Rich Editor which will destroy your code (this is currently the only work-around).


 * Since this image map editor did not allow the addition of the image name (it uses the supplied link information), the image name has to be corrected at this time.


 * Also change the image link from an external link to an internal link (remove the https....).
 * For example, if the URL in your imagemap code is " https://familysearch.org/learn/wiki/en/images/3/3c/ Mexico_states-1000px.png ?1406320063521",
 * you need to change this to "Mexico_states-1000px.png".


 * Also include the following code at the bottom of the edit page to designate a category for the template:  
 * Save the template.
 * You should see the image and when you put your mouse on the various areas you selected, you should see a tool tip with the title of the area.
 * Click on each link you created to ensure that they are functioning properly.

11. Limit the size of the image map

 * The image will be the size it was uploaded as.
 * If you want to limit the size of the image, go to the WIkitext editor and install a pipe after the name of the image at the top of the coding followed by the size in pixels, like so:
 * Image:Name of Image.jpg|400px


 * This specified size will be the image size that will be displayed on the target page for the template.


 * Note: Also see the Trick of the Trade below for an alternative way to size the image on the target page without returning to the template each time.

12. To install your image map

 * Install the image map (the template) on a target page like any other template.
 * Type            where you want it on the page.
 * If the image is still too large or you want to change the size, go back and edit the template by changing the size in pixels as in Step 11 or change the input parameter if the alternative coding method was used (see the Trick of the Trade ).

Note
An identified issue that may occur with the image map editor. Some people have encountered an unusual glitch wherein the "Href" and "Alt" information does not get properly recorded in the resulting wikitext code when adding polygons. This appears to be caused if the editor is not fully refreshed before each use (or if the page is refreshed or the browser is restarted with the page already open). At this time It is recommended that the editor either be reopened for each use or it can also be refreshed using the "online editor" link found in the left sidebar on the editor's page. If this occurs during use the Href and Alt information should be erased and re-entered which should properly put it into the code. The Href and Alt information could also be entered manually after pasting the code onto the template page. Please continue to report this and any other issues that are encountered when using this new editor.

Trick of the Trade
An alternative coding option for the imagemap extension
 * Are you tired of going back and forth between the page you are editing and the image map template just to adjust the image size?
 * Do you want to avoid making multiple copies of the same template in order to use the same image map on different pages with different image sizes?

By making a minor adjustment to the coding already generated using the image map editor, the image size can be selected while on the edited (target) page using an input parameter instead of accessing the template each time. For example, using the template call of will transclude the HubEightBullet1 image map that is 400 pixels in size.


 * Follow the directions above for creating the template coding using the image map editor by copying the editor code onto the template page using wikitext (not the RichEditor).


 * Replace the initial wikitext " " with the closing braces  }} 

In this example this coding will make the default size 640px if no parameter is used while allowing the image size to be changed to various sizes on multiple pages by using the template input parameter. Changing the image map size can also be changed at any time by simply changing the input parameter value on the page being edited.

See the template  HubEightBullet1 as an example of the coding changes. Within this template there is the extra code to display the parameter value (this code should not be included in your image map template).

Example of multiple sizing of the same image map template

Updating existing templates The older existing templates can also be updated with the new coding and if desired, the previously used image size can be used as the default value. For example, for a current image size of 640 pixels, the parameter default ( Image:image name.jpg | ) could be specified to be the current image size that was used in the original coding. This would ensure that the existing template calls would not have to be modified but could still be changed at any time simply by adding a new input parameter.

Quick reminder: The parameter input when calling the template must include the px after the image size number for the code to function properly. This is slightly different than the conventional use of the input parameter which may only require a number.

Example from Image Map Editor
Note: This is an example that was made using the original image map editor.

In this example, you will take an image of the Oregon flag and make it so that when you click on the image, you are taken to the Oregon page.
 * 1) Go to File:Oregon flag.png, and then click on the link to the file just below image to bring you to the page showing the full URL to link to the image.
 * 2) Right click the image and choose "Copy image URL."
 * 3) Go to ImageMap Editor and paste the URL in the URL field of the "Load from URL" box. Enter the full name of the image in the name box. In this example, the full name of the image is Oregon_flag.png.
 * 4) Click load
 * 5) The image will then load.
 * 6) Click Rectangle in the New Area box.
 * 7) In the link field of the General box, type Oregon.
 * 8) Next, you will set the clickable area that will link to the "Oregon" page. In the right upper corner of the image, click with the right mouse button. In the left lower corner of the image, click with the left mouse button.
 * 9) In the Global Settings box, click none.
 * 10) Paste your code in the appropriate location in the page. You should see something like this:

Save your page and test your link. If you followed the instructions for this code, you would see:
