Digital Visualizer
One of the benefits to digital photography is that the digital format opens up a variety of display options. Although you could print your pictures out and display them in a traditional frame, a digital photo frame will allow you to display your pictures by just plugging in a memory card. Digital photo frames, however, offer you a choice of storage, size and power options.
Storage
There are two types of storage in digital photo frames: hard drive and memory card. Hard-drive frames must be plugged in to your computer to load pictures, but can generally hold hundreds of pictures at a time. However, frames that take memory cards will need to have loaded memory cards stocked up with photos and then kept in the frame. Digital photo frames with ports work well if you have a few memory cards laying around the house, but if you don't have any to spare, it is more cost-effective to have a digital photo frame with a hard drive.
Size
Digital photo frames come in different sizes. The larger ones are surprisingly heavy, and you don't want to risk damaging your wall with nail holes trying to anchor your frame. So if you want to hang your frame on the wall, opt for a 8 by 10 inch or smaller size. Larger sizes are a better match for a table or shelf. Just make sure the frame has decent resolution (at least 480 progressive) to display the blown-up images.
Power
Digital photo frames can run on batteries or use an external power cord. If you are planning to keep your frame on a table, either of these power sources will work fine, as long as you are near an outlet. However, if you want to hang your digital photo frame on the wall, having a battery-powered unit is essential to avoid dealing with messy wires running down the wall.
