Remove slide show header from my gallery pages

I have a slide show header, but I don’t want it on my gallery pages because as my photos come up they hide behind the header.
I had Cinnamon Girls install my template and she set it up, I added more galleries. When I am on the dashboard I can not figure out where the slide show is to delete it on those pages. Thanks for any help you can give!

1 more Q: Any reason why my gallery pics/flickr are coming up in different sizes? Some come up so tiny and I have messed with the sizing, but it doesn’t seem to help. The blogger Gallery template was so much better. I am really bummed because I know WP is better, but my galleries is a big part of how I sell my business! Thank you!
