in one of my PHP projects, imagecreatefrompng complains, that the image “is not a valid PNG file”.
Warning: imagecreatefrompng() [function.imagecreatefrompng]:
'/.../...png' is not a valid PNG file in /.../...php on line ...
I’m pretty sure, the file is valid, because I can open it in any program. So I was wondering what else could cause this warning.
Does anybody know the details behind imagecreatefrompng or has had a similar problem before?
Thanks for your help,
Timo
Is it a PNG image? Run
fileagainst it, or try the fileinfo functions.
