    imagecreatefromjpeg not working

    hopefully this is an easy one to solve and I'm just missing something
    little...

    basically, I had a nice little website running with php, apache,
    etc... that uses imagecreatefrom jpeg to create thumbnails of larger
    pictures.

    recently, I upgraded my system from suse 8.2 to suse 9.0, so I assume
    my php/apache rpms were upgraded in the process...

    Unfortunately, now, imagecreatefrom jpeg no longer works on pictures
    taken with 1 of my 2 cameras - All of the ones with a Sony p30 work
    just fine, whereas if I run the function on pictures taken with a
    cannon powershot s400, execution of the PHP script stops. Nothing in
    the logs, nothing output to the screen, etc...

    Here is a snippet of code that I use:
    $size = getimagesize($p icturePath);

    $width = $size[0] * $x / 100;
    $height = $size[1] * $y / 100;
    $im = @imagecreatefro mjpeg($pictureP ath);
    $newim = imagecreatetrue color($width,$h eight);
    ImageCopyResize d($newim,$im,0, 0,0,0,$width,$h eight,ImageSX($ im),ImageSY($im ));

    If I put an echo right before and right after the
    $im=@imagecreat efromjpeg line, the first echo prints out, the second
    does not - so php stops parsing, executing the document.

    Again, this worked in the past, and I can't figure out why it wouldn't
    now. Here is some info from my setup:

    php 4.3.3

    Any help would be amazing - I've been banging my head on this for

      Re: imagecreatefrom jpeg not working

      One thought: Are the two files you're trying the same size? If one is
      significantly larger, it could either a) be larger than POST_MAX_FILE_S IZE
      or whatever it is in php.ini or b) it could be large enough that it will
      cause the script to timeout.

          Its a thought, but I'm pretty sure it isn't correct for 2 reasons:

          1) The script always worked relatively quickly in the past - it takes
          about 10-15 seconds to process 30 pictures... and the script is dying
          in about .5 seconds now...

          2) I'm not posting pictures - the php page is actually iterating over
          files in a directory that I choose, so it wouldn't hit the
          post_max_file_s ize.

          thanks though.
          mike.

              Hmm... have you tried writing a separate script that just tries to open one
              of the "evil" jpeg files, and on that one, don't shove an @ in front of
              imagecreatefrom jpeg() (so you can see what the error message is)?

                  Re: imagecreatefrom jpeg not working

                  Thank you - a brilliant idea... when I did that and and printed out
                  the return value from imagecreatefrom jpeg(), I got the following:

                  Fatal error: Allowed memory size of 8388608 bytes exhausted at
                  (null):0 (tried to allocate 9088 bytes) in...

                  So I went to my php.ini file and upped the max memory and now
                  everything works great. That also explains why my old camera (1.3
                  megapixels) worked and my new one (4 megapixels) didn't.

                  thanks again,
                  mike.
