When you are done typing the words you wish to post, then look at bottom. It will say "add file" click on that, then choose existing photo. Pick the one you want. Then hit INSERT. Then SUBMIT.
Hope this helps.
ALL IN 100%

Mr. VonHulk you forgot to ask what kind of device he has! Only apple and windows i believe can use that add file. Now as for android, lets see here, picart, photobucket amd i think tinypics as well. Hope that helps!
