OpenAsset allows you to quickly generate Contact Sheets that can be dowloaded as PDF files.

You can launch a Contact Sheet from either a filtered search or from a selection of images. Simply select the 'Contact Sheet' icon from the Action Bar.

Your 'Create Contact Sheet' page will open. On the right side, pick your page orientation, paper size, number of columns/rows, and what information you want included with each image. Then click the 'Create and Download PDF Contact Sheet' button. 

On the lower left you can save your settings so the next time you create a contact sheet, your document will already be configured.
