The software that came with the camera will probably do what you need, once
you figure out how to work all that stuff, yes, its true, you will need to
read the documentation.

There is a wide choice of software available, priced anywhere from FREE up
to several hundred dollars or more.

Look for Irfanview.

You need to get your mind (I assume you still have some functioning brain
cells) wrapped around resolution, compression, DPI and a number of other
esoteric concepts. Its confusing, but eventually you will be assimilated.

Have fun.

According to my calculations, 5x6 at 300dpi and 3 bytes per pixel comes to
about 8mb. I'm interested to see your reasoning.

Why do you want to reduce the size?  I know you way you are only
producing small prints, but what's the issue with letting it do it's own
thing?  Lack of hard disk space?  Small memory card?  Something else?
If it's lack of disk space and/or small memory card I'd advise getting a
larger disk and/or a larger memory card.  Cameras only come with a tiny
one, just enough to let you take a few shots the day you take it home
having forgotten to buy a big card. Remember, you can never put back the
detail lost the shot when you either shrink the result in your PC, or
instruct the camera to save smaller format images.  You never know when
one that you (or someone else) wants to print A4 will come along.

The mode you shoot in doesn't alter this BTW, just the results in the
images you save.

Are you running short of storage space?  Why not leave them as they
are?  You can print any size from any sized file, you know.
