There's no doubt this is a serious annoyance. Many people here want to see your finished model in its full glory, and you can't do that with 127 Kb. If you end up posting photos on another site or forum, please let us know.
There are other options besides Photobucket for third party photo hosting. Flickr.com and imgur.com are two that I've heard of but I haven't had time to examine how well they'd work with our forum. Has anyone else here had experience with these or similar sites?
