Hi Ameenah,
There are many differences between PC view and Mobile(Tablet) view. Per my knowledge, left navigation is invisible in mobile view(I did not test in a tablet, but i think it is same in tablet view). I suggest you switch to the PC View (if your browser
can support it off course) to have the left navigation in your table browser. Just hit the Options button at the top right > choose "Switch to PC View".
About responsive image for table browser, if you set the image with html, you are probably missing the viewport meta tag in the html head:
<meta name="viewport" content="width=device-width, initial-scale=1">
Without it the device assumes and sets the viewport to full size.

If you set the image with css, you can check below articles:
