When you’re making cards with your own photos, you’ll often want to edit the photos first. Professional graphic designers often use Photoshop although this can be an expensive route if you are just experimenting. If you aren’t doing this professionally then I recommend the Gimp.
The Gimp is an open source program which means that you can download and use it for free. This is what I use for all of my own photo editing. There are many online tutorials to help you get started with the Gimp. If you would prefer to start with a book, I recommend The Artists Guide to Gimp Effects.
