Photobucket's a heap of constantly-updating-itself rubbish. I've got two different computers that can't select direct links on there.
Flickr's gone and made itself slow, buggy, and looks asinine to boot. It eats my uploads every one out of three attempts.
DeviantArt's slow and has too many steps prior to images being uploaded. Once they're uploaded the linking process is a pain in the ass. (Have you tried, lately? Go try it. Seriously.)
...I guess I'll poke around with Ipernity a little more.
