I'm trying to find potential replacements for various Windows programs, and have hit a snag here so far (I'm testing them on an older Mac). XP's Windows Explorer handles huge directories of image files, displaying them as largeish thumbnails pretty fast. I think it "cheats" by only actually displaying what's on screen at the time, rather than trying to load everything at once. (It's pretty fast even if you disable caching thumbnails.) Anyway, I can't find a replacement for that for OS X. Finder doesn't do thumbnails like Explorer, and every program I've tried is WAAAAAAAAAAAAAY too slow to be practical. I've notably NOT tried iPhoto, as I don't have it (or at least not a current copy-might have some version 1 copy somewhere). I've tried Preview, Graphic Converter, Seashore, Carbonviewer (I think that's what it's called) and some others. They're all way, way too slow to actually work. This is completely weird, but...is there a replacement for Windows Explorer?
