Thanks for the trade info. To upload photos, go to your "settings" page. You'll see a button for "Photos." Upload your photo there, copy the link. Then make a new post -- hit the Image button and you get this:

[ img] [/img ] Note: I had to put some spaces in there for it to display the code.

Insert the link that you copied between the HTML tags and you're in business.

Thanks to Dynabolic who told me how to do it.
