Description:
------------
JPEG 2000 IPTC blocks are not returned by the 
GetImageSize imageinfo array.

This information is increasingly important with the next 
generation of digital cameras that will call for 
compressed, 16-bit files. 

Reproduce code:
---------------
<?php
    $filename = "iptctestimage.jp2";
    $size = GetImageSize ($filename,&$info);
    $iptc = iptcparse ($info["APP13"]);
    $title = $iptc["2#105"][0];
    print("Title: ".$title."\n")
?>

A sample JPEG 2000 image file is available here:

http://listera.org/pub/iptc/iptctestimage.jp2

This code is also available here:

http://listera.org/pub/iptc/iptctest.phps

A sample JPEG that does work is available here:

http://listera.org/pub/iptc/iptctestimage.jpg

Expected result:
----------------
Title: Title Metadata

Actual result:
--------------
Title:

Hello,

It seems that this jp2 image is broken. None of the tools I used to test can open it, even not the jp2 reference tools.

Which tools have been used to create this file?

Thanks for the speedy response! 

iptctestimate.jp2 was created using Adobe Photoshop and 
the j2k plugin. I have had no problems with these files 
thus far, opening then with OS X native applications, 
web browsers, etc. I have not been able to get tbe 
reference jj2000 application to run on OS X yet. 

Here's a new file to try, created using Graphic 
Converter:

http://listera.org/pub/iptc/iptctestimage2.jp2

Pierre: Please let me know which program you'd like me 
to try. Does the code actually work on jp2 files that 
you generate?

Most likely not, since the $imageinfo parameter of getimagesize()
is only supported for JFIF images.

Log: $imageinfo only supports JFIF
