The first generation of digital photo frames were introduced in the 1990s and included screens with the ability to accept memory cards directly from digital cameras. Digital photo frame apps are using this secure login protocol to eliminate security issues linked to storing login credentials. Instagram allow third party app users to connect to their Instagram photo content using OAuth to display photo content and authenticate without the app storing login credentials. In February 2008, a number of digital photo frames, such as the Insignia brand digital frames manufactured in China, were found to be carrying a Trojan horse dubbed Mocmex on their internal data storage. This can be avoided by buying a frame with an aspect ratio that exactly matches the camera, or editing photos to the target aspect ratio before transferring them to the frame. This could result in, respectively, images that are missing content, distorted, or which have blank space around them. (Sometimes 16:9 frames are actually 15:9) Depending on the model and features, images which do not exactly fit the aspect ratio of the frame may be cropped, stretched, or shrunk to fit. Common aspect ratios include: 4:3, 3:2 and 16:9. Ī new generation of frame companies, such as Meural, is emerging that combines larger formats, built-in access to artistic content, and innovative control mechanisms.

Some allow users to upload pictures to the frame's memory via a USB connection, or wirelessly via Bluetooth technology. ĭigital photo frames typically allow the display of pictures directly from a camera's memory card, and may provide internal memory storage.
