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.
Why not simply test the images to see if php opens them, if not divert to Imagemagick.
If your site is not particularly high volume, I'd suggest just using Imagemagick on all the images. You'll get better
quality and have more flexibility in handling them.
