Hi, just wondering how you get the actual picture of let's say a set, right when you click on the thread instead of having to click a link? All I have now are screenshots. What do I do?

Take the image you want and upload it to something like Photobucket or ImageShack (there is a direct hosting link at the bottom of each post) if it has not allready been uploaded. Then drag and drop the image into the url bar where you will just see the image / screenshot you took. Once you have that copy and paste the url into these tags . (Remove any spaces in the tags or the image wont work).
