Hi Ludovic,

I think you're wasting your time trying to protect pictures. If you use them, someone will find a way to copy them. Maybe you could come up with a scheme to scramble the pixels and then unscramble them in your program when you use them, but that is going to take a lot of effort and will really slow down the performance of the program at some point. I'd say you should just write a pretty threatening copyright notice and then make sure you follow up on it. That will scare most away. The others would take a baseball bat along side the head.

Just MHO,

Hello,

I'll have to made a CDRom (Mac/Win) with a lot of pictures.
All pictures are in a folder beside the app.

How protect this folder ?


I think it can be done. I would look at Revs encryption features if you want to store them externally. You could store them in custom properties in a substack as an alternative. This method must take into account available RAM and the effect of storing/calling upon data in this manner.

The short of it is: If is is truly necessary to protect the images you can provide a reasonable amount of protection.
