Could you mention from which script you are getting that?

Also, most of the time, its because your not referring to a class.

eg:
$classname->function();

This error usually appears when GD isnt installed OR GD hasnt been installed correctly.

You can use phpinfo() to see if php is compiled with gd support. Or from command line:

php -i|grep -i gd

If this error happens (mostly in the pixel selection) your GD library is not up-to-date or not installed fully. To create and read PNG images, the GD library supports normally the function imagecreatefrompng(). If not, your GD library is not complete.

Please ask your provider regarding this issue and ask him to add the PNG support to the GD library of PHP. He will do this. Afterwards, the error will not shown again.
