This extension adds the <imgcomp> tag which displays an interactive slider for comparing two images side by side.

Installation

  • Download and place the file(s) in a directory called ImageCompare in your extensions/ folder.
  • Add the following code at the bottom of your LocalSettings.php:
    wfLoadExtension( 'ImageCompare' );
    
  • Yes Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

Usage

To add two images to compare, use the <imgcomp> tag with these attributes (bold ones are required):

  • img1: The title of the image to the left ("before").
  • img2: The title of the image to the right ("after").
  • width: A number specifying the width for compared images in pixels. By default, images are added with their highest resolution.
  • mobilewidth: A number specifying the width of the images for the mobile version, also in pixels. If not specified, it will be 320 or the specified width if it is smaller.

The titles must not have the File: namespace. The inner content of the tag will be ignored.

Ideally, the two images should have the same width and height.

Examples

To compare JPEG example.jpg with PNG example.png:

<imgcomp img1='JPEG example.jpg' img2='PNG example.png' />

To compare Draft.png and Colored.png, with each image having the width of 400px:

<imgcomp img1='Draft.png' img2='Colored.png' width=400 />
