im pretty sure theres a thread about this but.. oh well lol theres a couple different ways, I do it by uploading the picture to a site like photobucket.com, and they give me the option to copy the link for the picture (to go to photobucket.com and see the picture) and the html code, the one you want is
, copy that and paste in the comment box and voila, when you post it the picture will show. i think the other way is with this comment box im typing in, (or anyone) on the top of the box theres a series of buttons and on is yellow/grey of a mountain and a sun/moon. click that and i think you can insert a picture that way. the methods are endless
