Shutterbugs, if you're a Flickr user, you have a reason to be snap-happy. Getty Images, a leading stock photo agency, teamed up with Yahoo this week so that it can buy photos from Flickr's 2 billion picture database. Don't go breaking out the champagne just yet, though. Since Getty will be handpicking the photos personally, users will have to wait to be contacted to discuss contributor contracts. If chosen, the Flickr image will have a special link to the Getty page. And while price has not been specified, they will likely be commensurate with current Getty rates.

Few places are more materialistic than Las Vegas, with its grandiose hotels and stacks of cash. But at last week's CTIA (Cellular Telecommunications and Internet Association) convention-which showcased several acres of upcoming cellphone and wireless technology-the focus was less on material goods than on what you can do with them. The exhibits boasted no gotta-get-it-now phone, but they did promise many ways to do more with the phone you already have. From file-sharing to postcard-making, the latest possibilities go far beyond mere talk.

My mom loves seeing my digital photos, whether they´re of far-off places or my latest culinary creations, so I´ve long thought about building her a digital-photo frame that would show a new shot every time she walked by. But instead of loading 1,000 images onto a hard drive, I wanted to be able to update the library remotely, adding new pics as I shot them, so she could always see what I´d whipped up that night or where I´d traveled that weekend. I also wanted the whole project to be cheap, because, well, I´m cheap.

A: Tagging is the act of assigning your own keywords to things online-photos, blog entries, bookmarks-so that you can easily categorize, locate, and share them in the future. One of the best examples is del.icio.us, which lets you save Web bookmarks to a page on the site instead of to a file stashed away on your computer. This way, you can access them from anywhere and let other people see what sites you like.
