If like me you can’t afford Photoshop at home, you should check out some of these alternatives. But perhaps you’ll have better luck than I did.
I’ve been intrigued by Aviary – not on the Six Revisions link above – but everytime I try to use it my computer becomes so unbearably slow that I navigate away. Sad because Aviary has three tools: Phoenix, an image editor; Peacock, a visual laboratory; and Toucan, colour palettes. When I did manage to use it without tearing my hair out I was annoyed that Phoenix had only a handful of fonts and didn’t allow you to use your own.
Still, I think it’s the best of those I’ve tried.
