@Sean You are correct about ARM architecture, didn’t do my research properly. I did a quick search and it seems like a hazzle indeed. This seems to be a kind of solution, http://mitchtech.net/dropbox-on-raspberry-pi-via-sshfs/
I agree about the space but if you have a decent sdcard, like 32gb you can store plenty of photo’s and change them once in a while. I have set up a shared directory with samba to the photo directory directly. I just put my photo’s in here and restart the pi.
Would be nice if google photo’s introduces an api, I use it for photo backup at the moment.
