I've noticed recently a lot of ppl still use photo hosting sites such as photobucket, imageshack etc... but these guys seem to be getting all nazi with copyright and other reasons to remove hosted pics.
Just wanted to throw it out there, that there are much better sites IMO for hosting all files (not just pics) and effortless linking to forums and the like.
Found DropBox to be excellent...
DropBox. Simply create an account & install a small app. It will put an icon on your taskbar which is a dynamic folder linked to DropBox site and is used just like a local folder. They give you 2GB (if you want more then you start to pay) of space to play with & you just drag & drop as you would any normal folder. Best of all, there is no moderation of files so you can upload to your ♥'s content. Also, there is no adware/spyware and the servers are lightning fast. To link a pic or file within the folder you just right click on the file=>Dropbox=>Copy Public Link and paste in thread post accordingly.
There are other good ones besides DropBox which work in a similar way, just Google it... but for crying out loud, give the photo hosting sites the big flick - I'm gettin dizzy with all the violation notices when browsing the forums, especially threads with NSFW pics!
