You are right in a way Mr. Blue Sky. The use iTunes approach does have several steps. Probably someone already familiar with Adobe Photoshop might feel comfortable doing it that way. y understan ding of that program is that it is comploex, but for somebodhy who has already climbed the learning curve on it, then there is another case. And, I simply cannot comment on any of the third party disk cover making utilities since I don't have (and for now) don't want any of them. Maybe that would change if I was making more disks.
Different readers of this thread may conclude that (a) they are already familiar with the iTunes functions mentioned here, or (b) that the time has come to become familiar with them. That was my situation, so this is one of those: "works for me" but may not work for you kind of situations.
Results? First of all, they arrive. (Basics are good to keep track of).
What about quality? A third party utility or the Adobe approach you have described will definately produce better results. But, for somebody who does not already have either Adobe or a third party program and only needs to make the odd cover every so often, no cost, use what you already have approaches are OK. In the meantime, a photo, sized to fit thejewel case is not all that bad of a fate. I think somebody could pull a photo into a box within MS Word and add text on top of that if they had the patience. (Not me, at least not yet, but the idea just now occured).
For my own part, I'm just now starting down the path you have already traveled and expect to spend some serious time "honing my skills" with iDVD and iMovie, so its pefectly likely that at some point I too would be interested in a more capable approach. But, for me, and at the present time, editing iTunes song info and attaching a photo to that is just fine. Maybe pulling the project into Word and setting up a template or 2 would work as well, but I don't want to invest much time in covers for now.
Thanks for challenging my beliefs, and good luck on your projects! Hopefully the other people on this thread will get something out of it as well. The old country folk used to say: "There's more than one way to skin a cat"!
