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.

If you're making web images, the dpi for the screen is 72dpi. End of story.

There's lots of settings within jpeg format. Usually the default gives the

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.
