Just below this post you’ll see an example of a Smilebox (a photo slideshow) that promotes a book signing. These slideshows can be emailed for free and posted on blogs like this or on Facebook and other sites. There is also a no-ads version that costs money, but I’ve always ignored the ads and used the free option.
Try it out, then go to Smilbox to join and download the free software. After that, choose a design whenever you want to promote some event or send invitations. It’s a lot of fun and very eye-catching. When you email it, it doesn’t clog the recipient’s mailbox, as they actually receive a link that takes them to the slideshow on Smilebox’s site. The original is saved there and can be used again later or revamped for another occasion.
