instead of just pasting your links in, use the [url= text[/url] function.
also, your link is fine most of the time when it gets shortened, it just looks truncated.
When you copy+paste a link and post it, it automatically puts [url] tags around the link. So it looks like this when you post it:
Code:
[url=http://i663.photobucket.com/albums/uu360/darthbeck/1293780323425.gif]http://i663.photobucket.com/albums/uu360/d...93780323425.gif[/url]
for whatever reason it decides to shorten the link, but click on it will open the url in a new tab or window. So does it really matter?
