I'm not sure I've seen this anywhere so I'll toss it out as a suggestion here. One of the things I store on my pics.livejournal account is my moodtheme images. In this case, they're pretty small pictures, all around the 30 * 30 range. When I view the gallery page for that gallery though, I see all the images blown up to 100 * 100, or whatever the thumbnail settings for the style I'm currently using are, which looks rather odd and ugly. So, my suggestion is that the thumbnailing algorithm should not blow up images, just shrink them for galleries which actually contain pictures (a behaviour which, when I get round to it, I'm going to mimic in a custom style). Any chance of that?
