Maybe I've found a possible solution:
In /vbimghost.php on line 710 there's the following instruction:
PHP:
$textcolor = imagecolorallocate($im, 0, 0, 0);
The Variable
$im used here is nowhere defined and/or set.
This Variable needs to be set with one of the
imagecreate*() Functions.
Also this could be a Typing Error, maybe the programmer means either
$img or
$img2 on this line.
Try changing it to either
PHP:
$textcolor = imagecolorallocate($img, 0, 0, 0);
or
PHP:
$textcolor = imagecolorallocate($img2, 0, 0, 0);
