For your second question, if you want to generate reduced-resolution
or lossy compressed versions of images you might try software such as
Gimp.  It is useful to have installed for many purposes, this being
one of them.  Imagemagick would be a good solution if you wanted to
perform this operation on huge sets of files, and of course ImageJ
would also be able to create compressed files for this kind of
operation.
