There is no way to track the images used. There file name must be shown on the project for our use, not published. There are too many projects to track the images when you shoot 10,000 every month. The file name is need to organize and manage the assets. Especially should there be any copyright issues. Need to know which image was used.

No I need to create a book in Indesign based upon slate projects. If I had the filename, the search would be easy No its a time sink to find the images used.
