07/04/2009  16:55               845 qjpeg4.exp
07/04/2009  16:55             2,032 qjpeg4.lib
07/04/2009  16:55           235,008 qjpegd4.dll
07/04/2009  16:55               848 qjpegd4.exp
07/04/2009  16:55           660,024 qjpegd4.ilk
07/04/2009  16:55             2,044 qjpegd4.lib

Yes, with .png it works.
