[RESOLVED] GD imagepng

[funkylizards]

I am trying to save an image file to the server with imagepng. The code is as follows:

$base = imagecreatefrompng($_SERVER['DOCUMENT_ROOT'].'/base.png');
...
some code
...
Imagepng($base);
Imagepng($base, 'new.png');

It displays the image, but doesn't save it. Am i using imagepng right? I have tryed:

imagepng($base, $_SERVER['DOCUMENT_ROOT'].'/new.png');

but that doesn't work either.

Is display_errors set to On and error_reporting set to E_ALL ? If so, have you tried commenting out the code to display the image (e.g. the first call to imagepng() above as well as any header() calls that set the Content-Type header) to see if there are any error messages being outputted?

I get:

Warning: imagepng() [function.imagepng]: Unable to open 'new.png' for writing in /home/*myusername*/public_html/create.php on line 6

line 6 being:

ImagePng($base, 'new.png');

Nevermind, I figured it out. I had to set the permissions for the folder to write.
