It's possible that a lot of people don't understand when they are hotlinking. I know I don't. When I post my photos that are on Flickr, I go to the image on Flickr, right-click the image, click "Properties," then copy the entire address (URL), and paste it in an IMG code here, like so:
Had I used  instead of (), and not deleted the colon after "http," an actual image would have appeared in that spot. Anyway, is that what is meant by hotlinking?
Archie Bunker: All I can tell you, Edith, is I'm surprised at you! Dragging me off to a moving picture like that! It was absolutely disgusting!
Edith Bunker: Well, I'm sorry, Archie, how was I to know? I thought it was a religious picture, "Cardinal Knowledge!"
