Yep.

I have an older frame that has an email option so people can send photos to the frame.

I bought it because it supports both USB thumbdrive and connects to SAMBA shares for photos, too, which is how I use it. Never even signed up for the service, and I've blocked internet access for it (bastardin' bastards designed the network stack to require DNS entries, picks).

The setup is annoyingly clunky, but once setup it does work fine.

My next one will start with a Raspberry Pi, then it's just a generic Linux box.
