Well, I threw this pack together based on a running joke of a server that I play on and decided I might as well put it up here, too. Not expecting many (or anyone) to use it, but hey, why not?
^Samples of some that I placed around the server as well as the wall itself I tested the pack on.
Since it's just paintings, it's super easy to put into your pack. Just save on of the above pictures as "kz.png" (no quotes), and put it in your art folder in whatever texture pack you're adding it to. If you don't have a folder called "art" (all lower case, no quotes), simply create one in whichever texture pack you want to use, and place the kz.png into it.
Me - My shoddy work on cobbling this all together.
Tombones - who made Gerudoku, for the painting back texture (since we're allowed to use his textures in remixes; it's infinitely better than the standard back)
Chaos - Whose terrible opinion inspired both the running joke on the server I use, as well as the pack itself.
Back by popular demand. In honor of our fallen comrade @ChaosLord121, this painting pack has been updated. It is now fully compatible with Minecraft 1.6, as well as all previous and future versions that support the kz.png art format.
