ExternalImageLoader allows for adding external images to your wiki. It allows you to pull images from external image hosting sites like imgur and embed them on your wiki page just like internal images. This also works with images on other wikis. This might be useful on wikis which don't allow users to upload personal images to the wiki ie. images only used on userpages.

Installation

Template

Copy the contents of Template:ExternalImageLoader to your wiki. The template usage instructions are mentioned on the template page itself.

JavaScript

In order to use this, put the following code in your wiki's Common.js. A helpful guide can be found here.

importScriptPage('ExternalImageLoader/code.js', 'dev');
importArticles — Best Practices for installing JavaScript on Wikia
The importArticles statement is designed to combine multiple HTTP requests into a single data transfer, allowing multiple scripts to load and execute faster. If you've been installing several different scripts, your JavaScript file has probably accumulated unnecessary import statements. Click "Expand" to learn how to efficiently batch import scripts to speed up performance and make your code look cleaner.

If your JavaScript file has several lines of code that say importScript, importScriptPage, or importArticles, you may be able to combine them! By batch importing a collection of scripts with a single import, your JavaScript code will load faster and look cleaner. Consider the example below. On the left is an example of what your JavaScript file might currently look like. On the right is how you could improve that code.
Multiple imports — messy and slow
One import — clean and efficient
importScriptPage('AjaxRC/code.js','dev');
 
importScript('MediaWiki:localScript.js');
 
importArticle({
  type: 'script',
  article: 'u:dev:FloatingToc/code.js'
});
 
importScriptPage('page1.js', 'wikiname');
 
importScriptPage('page2.js', 'wikiname');
importArticles({
    type: 'script',
    articles: [
        'u:dev:AjaxRC/code.js',
        'MediaWiki:localScript.js',
        'u:dev:FloatingToc/code.js',
        'u:wikiname:page1.js',
        'u:wikiname:page2.js'
    ]
});
Note: In this example, pay close attention to the placement of commas and other punctuation. For people who aren't familiar with programming (and even those who are!), a common mistake when writing code is to accidentally delete, forget, or misplace critical symbols like commas or quotation marks. This can cause a syntax error that breaks the code. Carefully follow the convention shown here when using importArticles.
But there's much more to importArticles than just this! For more examples and advanced usage, see the help page at Help:Including additional JavaScript and CSS.

Features

This extension works somewhat similar to External image whitelist but with lots of more customisation options (see the template page for more info) and the fact that you don't have to keep on editing ugly regex just to get an external image to work.

Example

This script can be used for animated images as well.

{{ExternalImageLoader
|url = http://www.mycathatesyou.com/wp-content/gallery/gifs/6.gif
|align = right
|alt = Thats how I do it
|caption = Thats my cat
|link = http://dev.wikia.com/wiki/ExternalImageLoader/code.js
}}
