I don't think so, or at least I've never seen such a function. But it's a good idea! Writing such a function with PEL shouldn't be too much trouble and would be a great example... If you already have such code, then please submit a patch at SourceForge, if not, then you'll have to wait until I get to look at it --- it's exam season right now... Some thoughts: Writing the headers back unchanged would probably be okay for most things, but a more sophisticated function would adjust tags like width and height, and maybe the digitized timestamp (maybe, I don't remember the exact conditions for updating it). -- Martin Geisler GnuPG Key: 0x7E45DD38 PHP Exif Library | PHP Weather | PHP Shell http://pel.sf.net/ | http://phpweather.net/ | http://mgeisler.net/ Read/write Exif data | Show current weather | A shell in a browser
