For some reason my avatar has changed back to the first pic I uploaded but I can't seem to get rid od it

I remove the avatar then upload a new one, it says i've uploaded but it hasn't changed.

hrrmmmmmmmmmmmm

It couldn't be because at first you could upload your avatars directly onto here, but now that option has been turned off... and you have to host your avatar on your own web space, could it???.

well that option was there 2 upload from my computer
