I tend to use:

For best quality printing or editting later 1 to 5% (assuming you need to
save space and do not want to use TIFF etc)
For viewing on PC or 'general' printing 10%
For internet 15 to 25 %

What is the best compression (1 - 100%) to use when saving a scanned
colour photo in jpeg?
I was to be able to display the photo on the computer screen and also
be able to print the saved photo on a inkjet printer.

If I have very little compression then the saved photo file size is
too big in size. Is there a general rule I can use to decide the best
compression to use?
