Is there a way, say using AppleScript to trigger a series of actions, to automatic relink graphics in a layout file? We often transfer InDesign CS6 layout file, with all its graphics in a folder, from computer to computer and links are always broken because InDesign does not allow relative file path for graphic files.
Why don't you us the Package feature and transfer the Package. The ID file in the Package will link to the Links folder in the Package.
We transfer InDesgin file (and its graphics) via a WMS system and routing these files are done NOT by a person, but a machine. It is the computer who is sending and receiving (not a person) and process InDesign files and no human involved here. Using package might be possible only if the machine knows how to handle the packages.
