Protecting Copyrighted Images Within Application

[Jean Christophe Avard]

Hi! I am designing a clipart manager that sells with over 1500+ copyrighted image. I want to protect these image, I read a bit about resource file, would it be the way to go? the image will be about 5 to 7 go... that's big, but it's the smallest we can go. (thiese are PSD format, so we can keep background transparency and a high resolution). Anyone has any idea to protect these? resource file or anything else... thank you!

Hello Jean,

I have done this with the sharpziblib library , with this library you can
create protected and compressed library`s

I can send you an example if you want ( the sharpziblib comes with full
source and is free )

no it's ok with the sharpzip lib, I already tried it, and I think it was YOU
that gave me code earlier this year. Anyway, the zip lib doesnt work since
we use psd file, and I have to rebuild the file but we only can go read-only
with the psd, so... anyway, thank you for your help.

I do not understand what you mean ..... isn`t PSD just a photoshop file ??

rebuilding the file ?? you mean writing it out to a file again ?? what is
the problem ?? this can be done

this is the part i do not understand


a resource file is definetly not the way to go as anyone can access your
files ,,, resource files are a nice way of grouping application specific
data

What is 5 to 7 go? Do you mean MB? As far as I know PSD (Photoshop
files) can't be passworded. And if you're providing a view of the file,
what's preventing someone from taking a screenshot? Maybe you should use
a proprietary format (i.e. invent your own). Or use an encryption
routine to encrypt the files that only your own program can decrypt.
