If imagecreatefromjpeg() is exhausting the memory you're not going to be able
to see it from memory_get_usage(); you'll be below the limit before the call,
and it'll die during the call - you won't be able to see it exceeding the limit
apart from the error message (you have turned error_reporting back up to E_ALL,
right?)
And next:
(1) What _is_ output by the script when it fails?
(2) Can you reduce it to a _minimal_ test script - sounds like it could go all
the way down to imagecreatefromjpeg() followed by imagejpeg() ?
(3) If you still can't work it out from there can you make available to the
group examples of (a) an image that fails and (b) a similar one that doesn't
fail?
