Digital photo frames' common sizes range from 7 inch (17.8 cm) to 20 inch (50.8 cm), keychain-sized. Some digital photo frames can only display JPEG pictures. Most digital photo frames display the photos as a slideshow and usually with an adjustable time interval. They may also be able to send photos to a printer.
Digital photo frames typically display the pictures directly from a camera's memory card, though certain frames also provide internal memory storage. Some allow users to upload pictures to the frame's memory via a USB connection, or wirelessly via Bluetooth technology. Some frames allow photos to be shared from a frame to another.
Certain frames can load pictures over the Internet from RSS feeds, photo sharing sites such as Flickr, Picasa and from e-mail. Such networked models usually support wireless (802.11) connections. Moreover, some digital frames now use cellular technology to transfer and share files easily and faster.
Most 7 inch (17.8 cm) models show images at 430 x 234 or 480 x 234 pixels. With some models the width of each landscape image is stretched to achieve an aspect ratio of 16:9, which results in noticeable distortion. Built-in speakers are common for playing video content with sound, and many frames also feature remote controls.
