Having the same issue.
PHP 4.3.11
Apache 1.3.29
libpng 1.2.1-2
libpng10 1.0.13-5
gd-1.8.4-7
JPEG, PNG enabled
Seems to fail on anything related to png code (ImageCreateFromPNG,
ImagePng, etc).
Works perfect using Jpeg.

I can not reproduce this with latest CVS of PHP when using
libpng 1.2.0 and GD 2.0.1.

Please provide a short, self-contained script which is as short as
possible, preferrably under 10 lines of code.
And such script which can be easily cut'n'pasted and run..
(without any need of huge rewrites)

This error occurs almost every time, once every 20 times it actually
works but most times it hangs.
Some times It actually finishes writing the file than it doesn't hang,
it just autopmatically comes up with the standard
-- Cannot find server or DNS Error --
there is no problem with the DNS it just gives that error when it
actually completes the file write.
if it does not complete the file write the file size of the created
image == 0 and the browser goes into a constant loading cycle, but
never loads the page.
Stats
Apache 1.3.22

The following function is usually called within a class, if that
matters.
it's not a bad piece of thumbnail code, feel free to use it at will.
Thanks
