I have around 100,000 product items with unique id-numbers that need to have corresponding images. As it is, there is no obvious correlation between image names and product numbers.
You will have no access to a database or code except from the public website (.jsp) itself, just like anybody has.
If of any help to you I have all the images copied with present names in structured directories.
Please have a look at the attached file and you will understand the whats it all about.
