When photos are backed up on Google+ photos...where do they go?!?

[AC Question]

I like that my photos are also backed up through Google+ (which is saved under my gmail account) my question is: why can't I then see the photos on that same gmail account when I'm on my laptop? My charging port is not working anymore (that can hopefully be fixed??) When photos are backed up on Google+ photos...where do they go?!?
