aloha, I am new to macs and am loving the challenge!!

In using aperture I have a project going from a recent wedding shoot where there were several cf cards loaded into the project. I have figured out auto-stacks, (kinda), and now that I have them in order I need to get all of the jpeg numbers in sequence so that I can upload them to my website in order. Anyone out there that may be able to help me out here? Also, is there any way to auto stack the entire folder so that the images will be order, one time?

Mahalo, Bboy
