imageshack.us would be my suggestion.
Imageshack is useful. But theres that problem of blockers at school and work for some of us.
So another place to go would probably be Photobucket
Catz
They both (imageshack and photobucket) are good choices. Even they re-size photo for screen view, you can click on picture to view it full size.
Thats great, just what i was looking for, thanks folks 
Hi, i've been working on a piece of CoH artwork for quite a while now and its almost ready to post. One thing i need is a little advice on where to upload to.. the image is large over 1024x768, but i want it to be viewed at full size when you hit the clicky.
Every site i've looked at so far seems to shrink the image etc.. any advice would be welcome. Thanks
