It's a good looking gallery.
Unfortuanately there are alot of reasons it will get rejected by TGPs.
Looking specifically at this version.

As ExtremeJohn mentioned many of the TGP scripts used, check the galleries for varius things. Brownie is notrorious for this.
One thing brownie is often set to check for is filesize for the fullsize images. While your images linked from the thumbs are good. You larger screensavers are too large and will get you rejected from some TGPs.
Another thing brownie checks is the number of outgoing links. Many TGP owners have this set to maximum allowed of 6. You currently have 5 outgoing links. Once you add 3 recips at the top you'll bring that number up to 8.
If your gallery makes into a reviewer submission queue there are several more items that will cause a reviewer to reject the page.
1 On my computer set at 800x600 I get a scroll bar. The page is just a bit too wide.
2 As mentioned your header is too tall without recips on a monitor set a 800x600 none of the thumbs are visible without scroll. Once you add a recip table you'll have the same situation at 1072x768. Essentially you have a FPA.
3 As mentioned the links to support and home are frowned upon and not nessary.
4 The banner in the lower left corner looks too much like thumbnailsl. This will get you rejected quickly.
5 You only have 14 thumbs many TGPs now require a minimum of 15 thumbs.
6 A picky reviewer might consider the screeshot picture of the screensavers to be a unlinked thumb.
My advice would be to reduce the size of the header. Plus revmove the extraneous links to home and support and revome the links to the screensavers. Leave those on your main page where they belong.
