Some people, apparently, have a LOT of time on their hands.
The issue is not hot linking per se ... it is hot linking to images you do not own or control. If you are linking to an image on your own website or to Photobucket or Flickr or some such personal image storage site there is no problem....or not. I figured this would be a good chance to learn how to post pictures, but I'm still stuck. Haha. When I click on the 'image' icon, I have to insert a URL, but I thought it's not allowed to link back like that?
