# 1. Plain HTML page with check-boxed thumbnail images
# 2. On submit() hi-res copies of the selected images are 
#    added to a .zip file
# 3. A new page is displayed listing the content and size 
#    of the file with a link to the newly created file
# 4. Once the file is downloaded it will be erased from the 
#    server. (better to prompt the user to erase?)
