IPTC image comments utility

Does anyone know of a utility for WRITING or at least reading IPTC data in images with PHP? I found lots of EXIF utilities and did an experimental thing with that. PHP even has a built in EXIF reader but the only IPTC utilities I've found are expensive ActiveX or Delphi components and I don't even know if those could be operated by PHP. THe one I used worked at a command line & I just did a shell command with a constructed syntax. Here's some stuff I dug up: COMIPTC 900 Euros http://www.j2s.net/EN/Products/comiptc.html Works with Visual Basic, ASP or PHP Matches Photoshop format Works on JPEG, TIFF, PSD TIPTC Delphi $566.60 <http://www.atom5.com/Development/Components-Libraries-for-Delphi/tiptc-delphi-component-to-read-and-write-iptc-data-from-jpeg-tiff-files-2620.html> JPEG/TIFF source code in pure Delphi code Atalasoft dotImage $329-$999 http://www.atalasoft.com/Components/dotImage C# ActiveX component .NET compatible many features AiS EXIF ActiveX $25-$99 (server) http://www.watermarker.com/exif-iptc-gps/ ActiveX component for Win9X/ME/NT/2k/XP Visual Basic, Delphi, C++, ASP, ASPX, PHP.
