I used to run a set of train tickets for the Polar Express. 27,000+ unique tickets, each with a different picture, number, car assignment, seat number, day, date and time and you impose within FP using their imposer software based on how you cut and stack and you export the single file setup as a PPML (.zip). CWS processes it almost instantly.
I'm NOT worried about the RIP. What I am looking for an answer for is: does FP have the ability out of the box to call back unique images from a hosted web server off site
