When looking at a list of edits, such as http://musicbrainz.org/user/aax/edits/open , there's 1+ page jumps when the images load. This is pretty distracting, esp if you're in the middle of writing an edit note, voting, or reading existing notes - ie, doing any of the normal things you would typically do on that page. The jump would be avoided if the img tag were provided at least a height (and perhaps a width, if it's possible; not sure if image dimensions are stored on MB's end) attributes, so the browser would have already allocated the space for the img.
