Hey All,
Running Redhat9, Apache 2.0.40, PHP 4.3.4.
GD support is enabled.
GetImageSize() returns FALSE on almost all JPGs, but does return with
the correct info on *some* JPGs. The array returned is empty.
This problem did not exist on my RedHat7.2, PHP 4.3.3, Apache 1.36
system.
I noticed references to this problem in earlier versions of PHP
relating to streams, but supposedly fixed. Still a problem for me!
Please help!
Thanks,
Jonathan.

Two things I can think off:
1) Are you sure they are jpg's, and not gif's that have "jpg" file
suffixes????
2) I believe there are different types of JPGs - I can't remember the
reason behind it, but I believe those that originate from Digital
camera's are likely to cause you the problem (though I have never
actually found the problem myself, I have read it somewhere (perhaps GD
info? Honestly... I can't recall at the moment). I believe jpg's
contain info (it can contain copyright info or some message text that is
not displayed when the image is displayed plus some other crap). I
believe the photos from *some* digital cameras do their best to create
small image files and therefore leave out some of this information -
This *might* be the cause of your problem.
Suggestion:
http://ca2.php.net/manual/en/functio...-imagetype.php
Run imagetype() against a 'good' image, and a 'bad' image and see if any
of the info returned after using the above function differs...
Lastly... if none of the above helps, might I suggest you post an update
on this post and tell folk exactly which version of GD that you are
using - I'm not aware of any problems with any GD functions that are
jpeg related, but someone else might...
Hope something above helps...
