 * A way to limit this to certain domains and even directories (and all subdirectories) of a particular domain
 * Allow image alt/title tags for descriptions, borders, and full HTML/CSS customization

Other URL types besides http:
We have allowed file:// urls to be linked from our wiki using $wgUrlProtocols, but this does not appear to apply to images. This would help us in our work to allow an image to be revised outside of the wiki on a file server and appear in a wiki article without repeated uploading.

 * So you want to put in an external image link but using a local file URL such as file:///h:\network-path\image.jpg  ?  Yeah you're right. I just tried that on my company wiki. MediaWiki doesn't pick up on the '.jpg' and spit out an IMG tag as you might expect.
 * It's a bit of an ugly thing to do, and highly non-standard. Internet explorer does support it though   . So you could make a simple mediawiki extension to output that HTML.
