Adding attachment

You are not doing anything wrong John, that method of posting pics unfortunately is no longer available,
you now need to use a photo hosting site such as photobucket and copy and paste the pic into your thread.

OK try this John, under your pic on Photobucket are 4 boxes, left click the bottom one (IMG code) to highlite it, right click then right click copy, come back to your post on ATF and left click were you want the pic to go (this will start the cursor flashing), then right click and right click paste, this should then show the IMG code, after you preview or submit your post it should show your photo.
