Setting your camera to low-res might be OK but if you wanted to have a hi-res picture but post it on the net too, you'll still need to reduce it.
Try this little program out, called XnView:

It's really simple to get the hang of, you can convert, re-size and do simple editing etc all very quickly and easily.
Have a play with it
