As far as graphic editors go, my favorite is Pixelmator. Most people don't need Photoshop but still want something that supports layers, does image manipulation basics and feels like a happy OS X citizen. On the other hand, GraphicConverter is the Swiss army knife of image formats and is even more powerful. GC can read virtually any image file ever created. It's a little more buggy, and the UI is less modern/fancy, but oh so handy.
