I don't know how the randomizer is coded.... but I just tested it with about 50 pages... I got the same four artists everytime and almost the same images from their galleries.
Monk-Monk/Dragon (12) (One single image appeared 7 times)
animegurl9405 (10) (Hers were all the same image)
themusicdied (37) (We got a good mix of hers)
Sinah (11) (I think we saw everything in her gallery twice.)
I saw ONE from Dennis
and One from Minimaid
and that's it. Have no clue what the randomizer looks at, but it got like stuck in a loop and began repeating itself.
I LOVE random boxes... so I was testing it to see if I could find some gems (and I DID, just from only those people mentioned above.)
Just thought I'd mention it, no clue how it actually WORKS
