The ProPack seems to have a problem with .png files created with Paint programs. I'll look into it if and when I get a chance. In the mean time: 1.)Render a picture of the item. 2.)convert it to an .rsr file with that converter program 3.)replace the old .rsr file with the new one (same name) When you launch Poser and open the library. Poser will convert your new .rsr to a .PNG file that it CAN read. ScottA
