It can't be lossless, and you wouldn't want it to be unless you want to give away high quality images for free. Most people with a computer (not high end users) have their screen set to a resolution of 800x600 pixels or less. More than this for web use and you're wasting your time for the majority of users. I try to keep my jpeg files inside 50K for general web use. You can make quite reasonably sized images on the screen that as a file are inside that limit. Waiting for larger files to download gets boring, and people on the web tend to have short attention spans. > To my present understanding, the only points in the workflow that you > have actual choice of dpi is at the initial scan, and at the final print. If you're making web images, the dpi for the screen is 72dpi. End of story. > When saving as a JPEG, different programs seem to have all > kinds of different specifications.

That would be best answered by someone who is using Photoshop Elements, otherwise I'd be talking settings which would make no sense to you. Rob
