Linkfo for Adobe InDesign
Linkfo plug-in labels all linked graphics in your document with desired information about the image and link. These labels serve as a quick visual aid for preflighting, searching for images and other operations which normaly require going deep into the panels and menus.
Labels are placed on a separate layer and can be deleted and re-created again with a single click. This means they can also be printed and checked in paper form. The information in the label is user selected and can contain info about the file, color and resolution and link status.
