    Sort by date picture taken

    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
    DateTimeOrigina l:
    DateTimeDigitiz ed:
    CompressedBitsP erPixel: 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 DateTimeOrigina l 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.

      Not sure, explorer may be falling back to a different value in the
      absence of DateTimeOrigina l. Btw, this tool can set the
      DateTimeOrigina l field: http://www.exifpro.com/Help/ToolDateTime.htm
