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.
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.
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.
This script can be used for animated images as well.
