Warning: imagepng() [function.imagepng]: gd-png: fatal libpng error: zlib error

Does this mean I can't rewrite pngs?

I just had that error with some code I was helping on not too long ago.

 

You are probably using the quality parameter but are giving it an invalid number -

 

quality

Compression level: from 0 (no compression) to 9.

 

Either they changed the range or the documentation was incorrect at some point in time.

[cooldude832]

so png quality is 1-10 instead of 1-100?
