A TOTALLY "FREE" program that was suggested here on Pet Talk ~
and I've used with Good Results is >>>

It doesn't have as many *Frills* & *Fancies* as the expensive
"you buy-it" programs -
but it works well for basic editing and photo touch-ups.

And - it's "FREE" - not a trial and gotta buy it later deal!
