Not efficient, because the actual size on the disk depends on the

excuse me but:
1. the OP asked for the size of the file, not the number of bytes it takes
up on disk (which are eaten up in fixed increments aka clusters) - then again
chances are the OP didn't consider that there may be a difference, so he'll have
to figure out which of the 2 number is actually important to him.
2. you don't seem to know what 'efficient' means, generating a wrong (in your
opinion) size consitutes wrongness not inefficiency. I called it inefficient
because it requires that the whole file is read into php's memoryspace.

Hi. Is possible to calculate the filesize of image that will result from
using imagejpeg without actually writing to disk?
Thanks :)
something like (although its not very efficient, I think):
ob_start();
image_jpeg($im); // $im is an GD resource
$data = ob_get_contents();
ob_end_clean;
$byteCount = strlen($data);
