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.
