That is my lib directory:

lrwxrwxrwx    1 root     root           13 Aug 19 09:31 libpng12.so -> 
libpng12.so.0*
lrwxrwxrwx    1 root     root           19 Aug 19 09:27 libpng12.so.0 -> 
libpng12.so.0.1.2.5*
-rwxr-xr-x    1 root     root       147704 Feb 18  2003 
libpng12.so.0.1.2.5*
lrwxrwxrwx    1 root     root           11 Aug 19 09:31 libpng.so -> 
libpng.so.3*
lrwxrwxrwx    1 root     root           17 Aug 19 09:27 libpng.so.3 -> 
libpng.so.3.1.2.5*
-rwxr-xr-x    1 root     root       147704 Feb 18  2003 libpng.so.3.1.2.5*

Should I link libpng.so to libpng12.so istead of libpng.so.3?
Or could I tell iscan to use a special library?

Thanks for your answer!

Florian
