Hi Angelo,
I used to have a same problem when I were programming MMS message parser.
You can find different solutions at the PHP Manual web site;
http://www.php.net/manual/en/function.imagecreatefromjpeg.php (check user
comments).
I've used one of these solutions but I don't remember exactly which one
it was.

HI all,
We have written an app in PHP4 that receives images from mobile phones that
are taken with the camera, we have found a problem that some of the images
are corrupt and we have determined that it is because of Nokia VGA cameras
that have sent the image, basically the jpegs are fine but the extra info
that comes with the jpeg is corrupt, therefore PHP wont open the image, with
all other photos its fine.
We found that i PHP 5 there is a setting that you can change to tell PHP how
strict to be when opening an image. That will work but now we'd have to
change the whole site to be PHP5 compliant and also test it on a new server
which is really alot of work and undesireable.
We also found another possible solution being that we use ImageMagick to
convert the jpeg to a jpeg, then it will load properly. But now we would
have to convert each image that comes in and maybe only 10% of the images
come from a Nokia VGA camera, ImageMagick also has to be run from the
command line (would this affect the performance of the site?). Would you
suggest using ImageMagick to convert the images each time a new one is
uploaded? Or does anyone have a better solution for this?
Thanks in advance.
