As CF card is rarely used by non-professional digital cameras, so it is often absent in low-end digital picture frames.

DPF-7003H (simple function photo frame) supports only SD/MMC;

7inch simple function frame DPF-7001 can be customized to support SD/MMC/MS with wooden faceplate.

Generally, simple function cheapest 7” digital picture frame supports only SD/MMC memory card due to the intense price competition and the low-end segment it targets to. However, 7” multimedia photoframe may support SD/MMC/MS(3-in-1), SD/MMC/MS/XD(4-in-1) in single card slot or even two card reader slots for SD/MMC/MS(3-in-1), SD/MMC/MS/XD(4-in-1) and CF card.

Larger size(above 7inch) photo frame often support CF card and they often have the other card slot for SD/MMC/MS/XD, some latest 8 inch digital photo frames come with only one card slot for SD/MMC/MS/XD ---without CF card.
