When choosing a digital picture frame, it is important to know what, specifically, is to be displayed. High quality digital picture frames have larger resolutions. Furthermore, digital pictures with dimensions significantly different from their frames may be distorted when displayed; a cheap digital picture frame with a 6x4 resolution aspect ratio might have to compress or stretch a panoramic 20x7 image to display it.
How the digital image is stored is also very important when considering a digital picture frame. Most digital picture frames have no internal memory, and require that a memory card, containing the pictures be inserted into the digital picture frame in order to work.
Every digital picture frame has one thing in common: they all require a power source in order to display images. Since the power source can impact long-term costs associated with the digital picture frame and where the frame can be placed, it is an important consideration when choosing the correct digital picture frame for a specific location.
