Whoops, sorry for the delayed response

Tricky -- i'm not actually sure what image formats are supported by  
CG, and i know less about what image formats are supported by the  
GTK, QT, and WX versions of webkit.

If you look at the arrays defined for supportedImageMIMETypes (see  
MIMETypeRegistry.cpp) we assume that all implementations support:
       "image/x-icon",    // ico
       "image/x-xbitmap"  // xbm

This only really applies to a standalone image -- eg. a person  
navigating directly to an image.

<img> tags just pass the raw data directly to the image library,  
regardless of mimetype so it's possible that more image types may be  
supported through <img> tags than as standalone pages.
