Well, I guess you have the biggest stereo, but can you explain how it works ? Is it implemented in your STD framework ?
We still have to support Windows XP so I'm not sure that PowerShell could apply for now.
We also considered to put the pictures in a PDF, but in doubt, we chose the simplest solution, which is to zip the BMP files (no need to install anything on the client, easy to code).
We'll see later, in use, if we need to improve with a third party tool or something.
