What I do is make sure my picture is very small. Big ones won't upload. Then I type my post and hit "go advanced" under it. The page will reload with a paperclip icon next to the smiley face icon. Click on the paperclip and it will open a field for you to choose the picture on your computer. Then, be sure to advance all the way to the right side of the page and click on "upload". Wait until it is uploaded. Then hit post and it should be there.
