there, all cleaned up. most of the stuff in your gallery was spam anyway.
now, to attatch a file you scroll down to 'Manage Attatchments'
click browse after that and you can then search through your computer to find the picture you'd like to post up onto this forum.
you can submit more than one picture at a time. once you are done click 'close this window' and the pictures, after you submit your message, will be there, beside what you have typed. ^_^
