Ok then, there are none. Sorry, but, the only "alternative" to Photoshop is either Lightroom or Aperture, the latter your best choice outside of Adobe. That's it. Sure, go ahead and spend hours learning some glitchy, not so well thought out software developed by a company that may very well not be around in a few years, or, is swallowed up by another company and changes it's culture and relationship to you on a dime. Trust me, the other software ditties mentioned in this thread are not even considered by pros, and pros are the market any developer develops for. Unfortunately, we are, and always have been, a small market, not profitable enough to warrant the investment by more than one company to compete. Even then, Adobe is always trying to grow into Microsoft or something, just trying to keep up with their Ferrari driving brethren in the Valley when it comes to stock price, by finding "business solutions". That's what it's all about, you know. The stock price. You don't really matter.
