Embed js/css but not images

[lornajane]

I have a presentation which has many large images in it. I turned off the "embed=true" in the configuration because it was resulting in a HUGE file because of my many large images. However then I got in a mess trying to back up my presentation - because I only copied my local directory, and it didn't have the avalanche files in. Please may I have embedding of all things text, but not images?
