So far I think this camera and library would be the best way to go about it since it has a nice up to date library for creating small or large images.

I did find a few ways to upload images from an SD card that worked so all we need to do have this camera save the pictures to an SD card and then push that image file to an FTP server using the code we already have.
You should buy the camera and do some testing for us 
Also, 4D Systems has a good forum with product engineers on there to help with questions or issues should they come up which is always a good thing.
