Until the GECK comes out this is the best I can do to replace the existing generic paintings. They are slightly higher definition than the existing ones and I have tried to correct the 20% difference between height and width which Bethesda in their wisdom allowed to get through.

Following the release of beta patch 1.4.124, thirty more paintings have become available to decorate your settlements. These are the twenty-three abstract paintings, seen occasionally in-game and seven post-war portraits.

I have now completed replacements for the above which you may prefer. This new download includes the original set from version 1.0, and so all you need to do is replace the Textures folder with this one. If you already have textures from other mods, you can open up the folders inside (SetDressing, PaintingsGeneric) until you come to one that doesn’t interfere with your existing mods.

Fourteen of the new set have connections to Fallout 4, though the links may be tenuous. It may be of interest to one or two people to solve the little enigma. 

There is an optional file uploaded which can be used if you find the current canvases too blotchy and pockmarked. If you download manually this goes in the SetDressing folder not the PaintingsGeneric folder.
