Hmph, that never even occured to me. I have "file manager hd" already installed, and it turns out to have a half-decent gallery feature built in (thumbnail browsing in the file explorer isn't too terrible either). I also tried something called "fish bowl photo", which is ok but still doesn't give the option to scale rather than crop thumbs. Also it arbitrarily selects images to display larger in tiled thumbs, when I'd rather they were all the same size until I want to view a particular one.
