Broken Links - Fix?

[محروم.كوم]

Hey guys, I recently deleted a thread and a slide show mod I'm running still shows the picture from that thread on the main page and so when users click the slide show to be redirected where the pictures came from; you get this:

Code:
No Thread specified. If you followed a valid link, please notify the administrator
So my question is, how do I fix it.
The main link is :

Code:
http://www.externalgaming.com/forum/...ead.php?t=4309
How can I remove it?

Thanks guys! __DEFINE_LIKE_SHARE__
