So, what image uploaders do you usually use?

Generally I used to use Photobucket a lot for my own stuff, but for a while now, it's been pretty sluggish and despite even paying for a Pro account, it still feels like a stick in the mud. I mainly use it only for signatures, which I can honestly say I haven't made too many lately.

Lately, I've been using Imgur for all the "little stuff" like funny animated GIFs and so on, and it's been pretty good. It seems quick and simple and I haven't had any issues with it.

So, which ones do you typically use and why?
