Different frames offer different ways of loading your photos, so you’ll want to check if it supports the method you prefer to use. More basic frames have a port for a USB storage drive and/or a slot for an SD card, so you’ll need to load your files to an acceptable medium and then plug it in. (Some frames ship with a modest-sized SD card for you to use.) Some frames have internal storage to transfer your pictures into; otherwise, you’ll have to leave your drive or card inserted. More advanced digital frames connect to the Internet and let you send photos via e-mail, upload wirelessly from your computer or smartphone, or link directly to your existing photo storage or social media accounts. Many of these web-based frames don’t allow for offline photo transfers, so it’s often a case of one or the other.
