I got an image, that is supposed to be PNG, but alot of applications can't read it (Windows itself can)... for example Paint Shop Pro says it is incorrect PNG, Chrome or Opera are not reading it neither... What is the problem??
Original image that is not readable by many applications, but is better looking than converted one with GIMP (smoother edges etc etc):
Converted image with GIMP, that does not look that good anymore (raw edges, doesn't look so smooth):
How do I make the first one readable without losing quality?
