It's merely a matter of file format support, Ron. Stay away from TIFF and PSD (Photoshop) if your planning on distributing the textures to PC owners -- they don't always work. Poser PP also supports the new .png format and Windows machines will work OK with it. BMP is an old Windows format (it means Bit Map Pic) and is a memory hog. It's only redeeming virtue is that both platforms will work with it. I would say that the best two formats are JPEG (baseline optimised and quality > 7), or PNG. PNG is lossless compression, whereas JPEG will always lose some picture quality -- even if you can't see it. Hope this helps you out.... Jim Moore
