Sorry but thats not what i'm after. I want to know the available memory needed to load the image. The default php memory limit is 8M and if the image is large php is not able to load it because the 8M limit is reached and therefore causes php to error out.
Is there a way to calculate the memory required to load the image without haveing to load it? Would the following work...
$memSize = $imageWidth * $imageHeight * 4
This assumes that gd uses 32bits per pixel.

William Bailey.
