Hi,
We occassionally get a PNG file whose thumbnail is discolored:
ex:
http://www.wikihow.com/Template:Fair-Use
vs original image
http://www.wikihow.com/Image:Red_copyright_213.png
We're using libpng 1.2.8, I assume it's a libpng problem? This image is an 8bit image it appears and when imagecreatetruecolor is used instead of imagecreate, the result isn't correct either.
Any ideas? Travis
