Since the great change of Alexander and Adam in January GNUstep no 
longer relies on on libwraster to load PNG (or other graphics formats). 
If you have a recent installation of GNUstep, it should be able to read 
PNG files as soon as libpng is installed and found during the configure 
process. If this does not work for you, you should recheck the configure 
log to see if something did go wrong at that stage. Otherwise it may be 
with the data itself. I only tested this functionality with PNG files, 
but it should work as well with data in PNG data. If your data wont work 
you could send on a (small) example file for tests.
