If you sigh your android device into google can your view what is in your gallery on your computer?

My tablets screen broke today (Damn) and I have a lot of photos that are in my android gallery I'd like back. I have plugged my tablet into my laptop but it says there are no videos of photos there, It does not show up ANY files what-so-ever.
I am sigh in to my gmail account on it? Should that help?

Please help me?
