Digital photo frames typically allow to display the pictures directly from a camera's memory card, and may provide internal memory storage. Some allow users to upload pictures to the frame's memory via a USB connection, or wirelessly via Bluetooth technology. Others include support for wireless connections or use cellular technology to transfer and share files. Some frames allow photos to be shared from a frame to another. Certain frames provide specific application support such as loading images over the Internet from RSS feeds, photo sharing sites such as Flickr, Picasa and from e-mail. Some frames also built for playing video content with sound, and many frames also feature remote controls. As for portable use, battery-operated units are also available in the market.

Aspect Ratio

The aspect ratio of the frames can vary. Common aspect ratios include: 4:3, 3:2 and 16:9.  Depending on the model and features, images which don't exactly fit the aspect ratio of the frame may be cropped, stretched, shrunk to fit. This could result in, respectively, images that are missing content, distorted, or which have blank space around them. This can be avoided by buying a frame with an aspect ratio that exactly matches your camera, or editing photos to the target aspect ratio before transferring them to the frame.
