I don't know why people keep bringing up GIMP. I didn't even mention it until other people brought it up. I certainly didn't recommend it, I just provided a list of free software alternatives to products like Photoshop. GIMP was on that list, but it certainly wasn't the only application on it.Actually, even though I'm a big fan of Open-Source, I still agree with Twiggy.
The GIMP only works good on Linux with the Gnome or Xfce Desktop Environment.
On KDE, Windows, and Mac, it either runs like ****, or doesn't run at all.
Besides, The GIMP is a huge bloatware, needlessly heavy.
Why do you think then I prefer Seashore over The GIMP?
