Well, let's see. I've got thousands of them in folders on my computer and backed up for storage. I have them in my screensaver slideshows at home and work. I've got some hanging on my walls. I put them in my online gallery. And most recently, I made a lovely 82-page book with over 250 photos that I can display on my coffee table in my entertainment room, and a copy which I keep in the waiting room at my office.
The book has been great - and I'm definately making more! Clients, friends, and family all love it - it's a good-looking, high quality book with professional binding, leather or cloth covers, title pages, etc. And it has actually helped me sell a few more photos, when clients leafing through the book while waiting have asked me if they could get some of the prints they saw.
I highly recommend considering one - it isn't that much more expensive than a nice photo album, considering the cost of 250+ prints and the photo album itself - my book was $80 total from a company called mypublisher.com, shipped to my door. If you were to print out 250 photos in random sizes from 4x5 to 8.5x11, it would cost $60-70. And it really has alot more visual impact than an album - people will think you hit the big-time!
