Many digital photo frames have a built-in memory so that you can copy photos straight from your computer or camera to the frame. If there’s no internal memory then you’ll need to leave your memory card inserted in the frame. If the digital photo frame has built-in memory, check the specification if you want to be able to copy between it and a memory card, as not all frames allow this basic functionality.
Digital picture frames can usually accept most types of memory cards. Popular ones include CompactFlash (CF), Memory Stick (MS), Secure Digital (SD), xD, and MicroDrive (MD). Check that the digital photo frame you plan to buy is compatible with the card used by your camera.
Here are common media card formats and their dimensions:
Compact Flash (CF) - 43 x 36 x 3.3 mm
Smart Media (SM or SMC) - 45 x 37 x 0.76 mm
Memory Stick (MS) - 50.0 x 21.5 x 2.8 mm
Memory Stick Duo (MSD) - 31.0 x 20.0 x 1.6 mm
Multimedia Card (MMC) - 32 x 24 x 1.5 mm
Reduced Size Multimedia Card (RS-MMC) - 16 x 24 x 1.5 mm
Secure Digital Card (SD) - 32 x 24 x 2.1 mm
miniSD Card (miniSD) - 21.5 x 20 x 1.4 mm
XD-Picture Card (XD) - 20 x 25 x 1.7 mm
Digital photo frames tend to have a fixed small amount of internal memory – typically up to around 512MB. By inserting a compatible memory card or USB device your frame's storage capacity can be vastly increased.
Memory cards are increasing in size all the time, so even if your digital photo frame comes with one it may be possible to upgrade to a larger version. 32GB cards are now available. This is enough to hold approximately 10,000 6Mp photos.
Given that the resolution of most digital photo frames is much less than the original photo resolution, there’s no benefit to putting 8Mp images, say, onto a 1Mp frame, as it is likely to slow the display down as it scales the images to fit. If you resize your images on a computer and put these onto the photo frame, you’ll be able to fit many more photos.
