Ok, what's up with the Pentax Photo Gallery?

I now have 15 shots up on the Pentax Phito Galery. The last three were all excepted. Something doesn't seem right here. Out of about 28 submissions, 15 have been approved. Out of those 4 are being used on product pages. I thought getting up there was a special thing. I'm getting suspicious about the voting process now. Does anyone know the facts behind this?
