Thanks bloodsong, That really sounded like it would work but it did not. Go figure. I guess the background is not saved as part of the image when you create a new library item. Jim, I don't think is really anthing "wrong" per se, I agree that something like this should work but appearently this is not an uncommon problem for items with a great deal of transparancy. It was the Daz tech support the recomended the RSR Converter routine. I contacted the author of that program on this issue too but he hasn't replied. Bottom line, I still don't have a solution. I suppose I could create a copy of each image paste them onto a sheet to reference but there has to be a way to get it into the thumbnail and I'd really like to find it.
