Is there a way to remotely (wired/wireless) update photos in a digital picture frame that doesn’t have any connectivity capability? All it has is a USB port and sd card port.

They make wireless SD cards. Pretty sure USB drives too.
Or you could build one yourself with a raspberry pi or something. I’m sure there’s a way to present its storage on USB, then add wifi for you to access that storage.
You could use something like the Toshiba flash air?
That probably doesn’t work unless you power-cycle the picture frame after changing the photos.
I had this with some offline Samsung picture frame and a Transcend WiFi SD card. The SD card runs a small Linux and can be unlocked to add own scripts. I had a script that would rsync files from my storage to the SD. However, while the new files were written to the SD just fine, the picture frame never re-read the list of files from the SD. And after power-cycling, my specific model needed to be turned on manually again. So, that wasn’t a satisfactory solution.
A smart powerplug and/or a fingerbot would solve that problem I guess? But at that point it’s probably cheaper to buy a network connected picture frame.
