I have tried everything downgraded or upgraded to slashdots php install
still no luck it acctually appears to be a write error but i have given
the file permission to Adequately destroy my whole system if a haker
gets in.
scipt execute read write delete ect. I am a newbie to PHP that is
probably why this is in the wrong area but the condition looked simular
to what I am facing. I have no ability or knowledge of how to recompile
php. Do you have any suggestions. using included php_gd2.dll

The functions ImageCreateFromPng, and ImagePng are missing
so generated grahics cannot be used with GD1.6 and above.
Please find attached a diff which adds these functions.
Hope this help - Drew
