The use of photographs for cover art is something I am never going to love.
Same here, but for me, that's mostly because lots of artists seem to want to design covers like movie posters, and both end up suffering from the "photos of the main characters posing and maybe something else remotely relevant in the background" syndrome which I find utterly boring.
If book covers were approached more like album covers, I might care.
As it is, I don't really give a shit about book covers. They don't affect me one way or the other.
