Just bought a DSLR. The jpg file size is big when we use the highest setting to shoot. It is 9 to 10MB each. I would like to find a free (not free download or trial) software to do some simple editing like cropping, adjust brightness, hue etc and most important able to compress the file to smaller size, (preferably less than 1MB each) such that I can send them to my friends and families for viewing.

Any suggestion?
