Martin, you're a genius. :-) I installed a minimal Quicktime on my work machine, which had never had it since I reformatted. I included the 2D image support, and - hey presto! Poser can now see Mac image formats. My home machine has Quicktime already, which is why it works there. I think that just about wraps it up. To summarise: * Don't include calls to Mac formatted image files in anything you distribute. * If you have trouble reading Mac images, install Quicktime. Thanks all, and goodnight!!
