How To Make a 2D Image Imported into DAZstudio iRay Friendly?

What I want to do is paint an art painting (with my actual hands and a real paintbrush and acrylic paint), then photograph it with a digital camera, then import the image of the painting into DAZstudio, and position it in a 3D room on a wall like a real painting would be hung.

I assume this painting would be considered a texture/material/shader in DAZstudio, if I applied it to a plane or cube. 

My question is, how can I optimize this painting for rendering in iRay?  What do I need to adjust in the Surfaces pane?

Thanks!

    There are several ways to go about it. You could apply it to a primitive plane, and then just apply some surface settings that mimic a painted canvas. Like a glossy fabric, maybe? It depends on your paint. Another thing you could do is once you have a photo of your painting for Daz, run that picture in a free normal map maker like http://cpetry.github.io/NormalMap-Online/ and make a normal map so the paint will have realistic surface (especially if it is a thick paint like oil.) That link can also make bump maps.

    There are some products that have canvases and frames in the store, too. http://www.daz3d.com/collective3d-create-a-room-xpack-1 has some, and this item focuses on frames http://www.daz3d.com/everyday-frames-mirrors

    what I do is 
    1) create a primitive of the appropriate shape
    2) apply the image as texture 
    3) apply the default iRay shader 
    4) change glossy color to black
    5) add the image to emission channel if it is meant to be a backdrop so realistic light comes out which you won't do in this case.
    6) you might apply ithe imape to the bump or as mentioned above as a normal but normally I don't bother unless the image will be close enough to see the texture (Like a Norman Rockwellesque child with a dripping ice cream cone reach out to touch a Jackson Pollack as the terrified guard rushes to stop the disaster(.

    I think you will be best off to load a jpg as a diffuse color map in the surface of a primitive plane. If you put a shader on the surface, then you will need to laod into the base color map and your painting may be dull. See examples (same lighting)
