Go to the photo gallery.
Upper right corner is an "upload" button. Click it.
Select a category/folder to put your pics in. Gotta do that every time as it defaults to DML member bikes.
Type in a caption and keywords if you like, the click the "post my picture" button at the bottom.
Wait for it to upload. Repeat as necessary........
Check your picture size before sending, I think the limit is 500kB or so. If the pic is too big it'll hork on it. Resize your pic if necessary.
