I think you're overestimating the problem where books are concerned. Sure, I've seem some bad photoshopped covers, too, but publishers are still putting out some very striking covers as well. I've been very happy with the covers I've gotten from Tor's art department in the last few years. Just go on amazon and check out the covers for Only Superhuman, The Six-Gun Tarot,
and Other Kingdoms.
And those are just the books I edited . . . .
Nightshade has been doing some gorgeous covers, too.
