First, this is not about how to fully, automatically integrate CS and Drupal. That would be nice, but I don't think there is a way yet.
Instead, this is about my experience recently as I obtained Adobe Dewsign Premium CS4 and started to learn it.
I have been using CS4 for several months now. I started my graphic editing with GIMP, an open source competitor to Photoshop. I got an opportunity to acquire CS4, so I decided tos ee if it was all that much better than something like GIMP.
