Need advice on taking doll pics

I love doing photoshoots of my dolls, but I'm very new to anything but just snapping a pic of the kids or something like that. I have a kodak easy share digital camera that is about 5 or 6 years old. I do have gimp, but not really sure how to use it.

Any tips/tricks or links that might be of use to me would so gladly be appreciated by me and my dollies.
