Attachments and thumbnails
I never really noticed too much before, but I'm on a slower computer at the moment, so it's starting to affect my browsing.
I was browsing a FS thread, and the thumbnails attached were taking forever to load. When they did load, my browser was scrolling very slowly through them.
I checked the source of the page, and my suspicions were confirmed: the thumbnail is the exact same image as the full size, just with a height and width property set. So, it's pretty much loading the whole image from the get go, and displaying a ton of them as thumbnails, taking a bunch of memory to handle.
I'm not sure if it's a fluke, or what, since I haven't noticed it before. I guess the slow computer I'm on brought it out.
I'm not too up on ColdFusion, but I know PHP and a few other languages have a library for making thumbnails on the fly. I have a gallery set up at home where I did this using PHP.

I was all for having to resize when you first post them, not after a re-edit... but this idea you have seems good too, especially for people with large images. But sometimes, even with the thumbnails, it'll still slow down. There was a lot of times that I was on a forum, and there was these images loading and took forever. Only AFTER they got done loading, they turned into thumbnails. =\
