I recently took photos at a fashion show (don't ask) and wanted to send a few dozen of them to a friend. Rather than exporting all these individual jpegs, I wanted to put thumbnails into a single file for easy viewing. I could not figure out how to do this. As LR is an Adobe product, I am surprised that it does not have PDF support built in (or I am missing it). The Print module will do just what I want, but only to paper. Tanks for any ideas.
Not built in, but....
I have Acrobat and can select the 'Adobe PDF' "printer" to create a PDF in LR.
If you Google 'PDF creator' you should find a free one which works.
