Subject: Re: Exif Tag Remover

Date: Mon, 24 May 2010 18:47:45 +0200

Hi,

I'm going to let you in on a secret: Exif Tag Remover is based on ExifTool. It's basically a front end, specialized on easy removing of metadata. In the first version I actually did the removing with my own code, but Exif is a pretty complex format and my code was not working very well, and then I found ExifTool which had a very generous license so I decided to change to that.

So my knowledge of Exif and IPTC is not the best actually. I am pretty sure that ExifTool can help you. Perhaps you can write in their forums about your problem (with an example image)? The author seems very helpful.
