What is a PNG file? ALso, I recently DL'd some freebies and unzipped them into Poser4, but I cannot get them to work. All I have in the library sidebar is an image of a bloke holding up his hands!!.. How can I get the library images to appear (I've not had this before!!). Am I putting the files in the wrong directory. Second, I keep geting "out of memory errors" when trying to load any of these components. Any help would be appreciated. I am desperate to use these products!! (Shows how sad I really am)LOL. Thanks in advance.............David
