Picture Album plugin

I am looking for a picture album plug-in that will automatically create thumbnails and then can be put on a page instead of a post. Also, that can be updated when I get more pictures. I am using Simple Popup Images, but when I just went to edit the page to add more photos, I realized that you can’t do that…It will only let you post them in a new page or post. I’ve tried about 4 different other ones, but nothing is quite what I am looking for. anyone have any ideas? Thanks so much.
Oh, and here is my site in case you want to take a look to see what I am talking about.
