You’re welcome! There is quite a bit of info on GIMP already scattered across this forum, you should be able to find some pointers somewhere!
Here are a couple of links to get you started:
- And a couple of tutorials that I have made: http://snowflake.nfshost.com/web/gimp-tutorial/basic-photo-touchup-gimp.html
Some of these posts have other links within them, so that should give you a pretty good start!
Of course, if you have questions, don’t hesitate to ask!
