To download GIMP go to http://www.gimp.orgThis video was created using GIMP 2.6. The current version is GIMP 2.8 from the release notes many of the issues that I have had with this program have been resolved. So get the current version and you will be pleased with the choice.When saving your final product, the native file extension is .xcf this file will save all of the layers and be editable.To save the file into your header you will need to export it as a .jpg or .png file. Saving in this format will flatten the file and make the picture one single layer.Save both so that you can go back and edit your picture later if you want to change it up. Upload the .jpg to your website and you are good to go.I hope you have enjoyed my tutorial. Please click on the Like button to show your support. Feel free to follow me.Labman (Craig H.)
