Question

I saw that you can embed meta-data into images very much like you can in mp3s, here.

Can someone point me to a tutorial of how to embed and read this sort of information w/ photoshop and flex together?
I really wouldn’t know where to start… Tried googling but I’m not sure I have the right keywords down.

Thanks!

Photoshop (CS4+ I think) can also add XMP headers (XML style) which will be easier to parse than bytes but it contains different information.

Here is a class that should do the job. It is non-commercial only but there is another option.

Here is a php script that will do it that could be ported to as3 – it might be easier than creating one from scratch. If you did want php to read the info I would use the built in exif functions 🙂
