If you're like me, sometimes it's hard to get a good idea of what your best photos are when you're looking at them on the screen. Sometimes it's good to get away from the computer, and look at paper. While I always advocate "staying green" and avoiding paper where possible, sometimes clients (or grandparents) prefer things the old-school way. Professional photographers use "contact sheets" which are sheets of paper with sample images on them, much like you may have seen "thumbnail galleries" online. A contact sheet is a paper version of a thumbnail gallery. Adobe Bridge features a really easy and customizable way to view just the images you select.
Open BR CS4. Select "output" from the top row, and you'll see a dialog box on the right hand side with multiple sets of options. At the top it asks if you want to output to a pdf file or for the web. According to what output options you choose, you can customize the way you want it to show up.
You can see a couple of samples here; a contact sheet with 40 smaller images, or one with 20 larger ones. You can choose whatever sizes you'd like, or use some of the more common presets.
