What content-type is returned for the PNG images? If they are stored as 
File or Image objects, you can see this on the Edit tab. If it doesn't say 
'image/png' then this is your problem. IE5 makes it's own decisions on the 
content-type based on the extension, while most other browsers (correctly) 
take the servers word for it.
