Adobe Elements 4.0 Save Dialog Box?

Question

I have a question about the options presented here: baseline optimize, and the one after (don't have adobe up and running right now). What do these options mean, to the lay person?
Thanks.

Answer 1

Baseline (“Standard”) Uses a format recognized by most web browsers. Safest to use.

Baseline Optimized Creates a file with optimized color and a slightly smaller file size.

Progressive Displays a series of increasingly detailed versions of the image (you specify how many) as it downloads.

Not all web browsers support optimized and Progressive JPEG images.
