click the actual text "Write something" toward the top of the page. For me, sometimes this did absolutely nothing, if that happens refresh the page and let it load completely before you click anything. When it works you wil get a small set of icons that appear underneath the dialogue box. Click the one that looks like a picture. That should open another small window that allows you to browse your computer for the pic you want to upload. Don't feel bad it was a PITA for me, I tried two different browsers and in pure frustration I clicked like I was trying to beat the "Write something" into submission, and the icons appeared!
...and then promptly went away because I had already clicked again
at least I knew I was getting close. a refresh and one click did it from that point.... Good luck.
