Prevent imagecreatefromjpeg from stopping script

Question

I am using imagecreatefromjpeg on a shared host, so if the image is to big then imagecreatefromjpeg will give me an "out of memmory error" and terminate the script.

Is there anyway to catch the out of memmory error, and simply let imagecreatefromjpeg fail(Return false) instead of terminating the script?

Answer 1

Try working out the size of the image first: http://uk3.php.net/function.getimagesize I believe imagecreatefromjpeg will fall over if the image is bigger than 3000px in any dimension.

see this thread:

simple answer is its not easily possible with any degree of certainty

Answer 3

does adding @ before the function do any help?

example:

$x=@imagecreatefromjpeg .......

Answer 4

Simply enclose your function inside if statements, instructing it to redirect when the function fails.

i.e. if (!imagecreatefromjpeg){//redirect commands here};
