Hi,

I am displaying a bunch of pictures on my website and I would like to
sort them by a Date Picture Taken key. I have looked into exif data
and I wrote a little code that just prints all the keys and their
contents.
Code:
$file = "MyPicture.jpg";
$exif = read_exif_data ("$file");
while(list($k,$v)=each($exif))
{
echo "$k: $v<br>\n";
}

For date picture taken, All I get is:

FileName: MyPicture.jpg
FileDateTime: 1180959961
....
ExifVersion: 1220
DateTimeOriginal:
DateTimeDigitized:
CompressedBitsPerPixel: 892484151/3289658
....

nothing as you can see. Here is the info from phpinfo about my exif
setup:
exif
EXIF Support enabled
EXIF Version 1.4 $Id: exif.c,v 1.173.2.5 2006/04/10 18:23:24 helly
Exp $
Supported EXIF Version 0220
Supported filetypes JPEG,TIFF

When I download the jpg, I can view/sort by the date picture taken
using Windows Explorer.

Does anyone know why I am not seeing the DateTimeOriginal information?

If anyone knows a better way to sort by Date Picture Taken On, I'd
love to hear it. Windows can do it so it must be in there somewhere.
