Image Gallery Problem

Having a problem with my image gallery.

1. Each is showing up as an updated on my main page- how do I make it so it doesn't publish each on to the main page- it only creates the image gallery?

2. It shows up fine in FF, with 12 on page- it wraps at 4 images and shoots the next one down. On IE it puts a fifth on the line and winds up going under the right side content. No clue why.

I am operating on kcrockyhorror.com and happy to give any info I can.

Thanks.
