I used to be able to access the Mudcat photo page. With the machine and browser I normally use, I can't any more. MyOpera has fucked it up (the pictures are only accessible via some non-portable Javascript, the images don't have direct URLs).

Flickr is another inaccessible picture site, for the same reason.

Photobucket works fine though. Also lets you provide a direct URL for the image itself, which is by far the fastest way to access it.

Bert's site also works like a dream.
