Kiz has made a post about how to post pics but it might be handy to have one at the top of each sub forum that has pics in it.
Firstly go to imageshack.us/ and upload your pic. Copy the url to the direct link.
Click on reply then type in then copy and paste your url then type in [/img*] but without the * as I put that in there to stop it working. Your pic should come up.....if it doesn't it's not my fault haha. ;D
