additional information in image-files

[chrispi]

Hi, I am pretty new to sw-developing and I want to add some additional information to different image-files.
As I know an image-file is just some tags with information and it is binary.
How can I find the different tags in such a file to find the right place for adding my information?

I suppose you mean to use Jpeg image files. I know that in jpeg header there are some additional information (exept from size, color model etc), that have to do with copyright, author etc. I found this (http://www.codeproject.com/bitmap/iptc.asp?) link that may help you: it is a program for manipulation of image information from jpeg files.

Hope this helps. :wave:

A standard for storing information in images is called EXIF: Exchangeable Image File Format. You can find more information on http://www.exif.org/.
