[quote author="n0xie" date="1294852377"]Why are you randomly generating id's ? Wouldn't a primary key or the use of uniqueid() solve your problem?[/quote]

If I'm understanding function of uniqueid() its for generating IDs for storage in the database ? What I'm doing is getting random entries that are already in the database to be put on a page via thumbnails with info, stuff to get the guest to click on through.
