Image resizing

[timlondon]

I'm having problems using GD to resize large images (2mb +). Is GD the best way forward for this or should i be using something like Imagemagick?

As far as I know GD should be fine with that - however PHP it's self might be the cause of your problems. PHP is only allowed so much RAM per page request. You might need up to 6MB to process a 2MB image, and yet your PHP memory_limit could be set to only 4MB.

do you mean the ini files resource limits? They are set to:

 

max_execution_tim = 30

max_input_time = 60

memory_limit = 32M

I've increased the memory_limit to 128 but the problems still there.

 

I think i've isolated the problem to a copy failure.

 

$newname="../../mbr/".$fl."/".$detail[0]."/Imagetmp/".$image_name;

$copied = copy($_FILES['image']['tmp_name'], $newname);

if (!$copied)

{

echo 'Copy failed!';

exit;

}

 

The above works fine when uploading images under 2mb. But any image over 2mb gets a coy failure.
