Any particular reason you don't want to use Flickr? Aren't they specifically set up for that?
If you're worried about file sizes, Flicker should be fine for people to browse your photos, and if you want to send them large files, services like yousendit.com should suit your needs for that just fine I would think. If I remember correctly you can send up to 100 MB for free.

I'm not likely to be around much longer. As before when I first signed up here years ago, I'm finding that after a long hiatus, and after only a few days back on here, I'm spending way too much time here again already. So I'm requesting my account be locked, banned or whatever. It's just time. Until then, well, I dunno...
