I just did this so I could explain to you how I do it, Click "post reply" then click on the "paperclip" to the right of the smiley face. Click the "browse" tab, find the pic on your computer, double click the pic, click the "upload" tab. When the pic is loaded, I close that window then click the "down arrow" beside the "paperclip" the click "insert attachments" Try that.
