ind & indd - Adobe InDesign
Adobe InDesign use a fragmented internal storage which will disassemble images, so they are not stored in their original format. File Juicer will not likely recover those directly. If you have Adobe Indesign you can print the indd file to PDF and File Juicer can extract the images from the PDF file.
You can download a tryout of Adobe Indesign (at least when I wrote this page).
