You would not think this is so tough. Anyway I am going to a mountain cabin where I think it might be difficult to use Google Drive to deal with pictures. Simple me thought I could use my Linux laptop to accumulate pictures from the Nexus 4. It takes good enough pictures for me.
So, there are countless methods to do this, and they all don't work! I know, I tried them all. Finally I got the recipe:
Get the binary of go-mtpfs. Put your user in the fuse group. Make a directory for the mount. Just execute the binary (having made it executable - Ha!) with the mount point. Yeah, you can see all the phones files!
