IPTC headers form Images -PHP slow/fast?

[torbjoen]

Hi!

Does anybody have an idea of how I can extract IPTC-headers from an image file?

I'm thinking of making an image gallery by storing images in various folders. A php-script would then run through the folders, reading IPTC-headers from the images and displaying the information.

Also, I would like to make a search engine for the gallery - one that searched through specific IPTC-headers of all the images in all the folders.

The IPTC-header search engine - will it be very slow when using PHP to search through the IPTC-headers? Should I use Perl (if there is functionality for such) instead?

I'd appreciate any source code on the matter!

Best regards,
Torbjørn

Someone got an idea? Specially on getting special chars like ë and é and à out of IPTC fields?? Got strange problems with it... thanks.

Try googling for "IPTC character encoding". In short, the character encoding should be specified (at least if not US-ASCII), but generally isn't, and by then could be anything. If it's not US-ASCII (which it obviously isn't) I'd start by assuming it's utf-8, or if the metadata was generated on windows (at least older windows versions like XP) ISO-8859-1.
