If you're one of those people that uses photobucket and haven't moved to flickr yet, or still aren't happy with flickr and want something else then maybe go and check out www.shutterbook.com
They are offering free lifetime memberships/premium accounts to anyone that joins while they are still setting things up. I don't know much about the details of the site regarding large images and bandwidth but I've uploaded one image and it came up just fine when testing it on lj. To get the url to an image you have to right click and open in new window.
Oh and everyone should go join the polaroid community polequalsart. I only just recently became a co-moderator to help out with a few things. It's just starting out but some of the polaroids on there are really nice.
