Obviously not a major problem, but recently, every now and then one or two avatars may not display on the page unless I refresh. Could it be a problem with my browser?

Bump! Just scrolled down a page where 1 of 8 user's avatars displayed.

Have noticed this too, thought it was just me :S

There's been a few little things like this happening with sigs as well.

Also images within posts, will randomly show and then will just be a ? box or a x box.
