Answer 1

It looks like your image is not resizing.
use this in your css style
.boxpic img {
width:100%;
height:auto;
}

Answer 2

Add the following class to your images:
img-responsive
An example is below:

Also, BootStrap works from a bottom-up sense... meaning, if you declare the columns to be medium, then both medium and large columns will stay consistent with what you declared, i.e:
col-md-3 therefore implies col-lg-3
Whereas if you declare an extra small column size then that stays consistent with every column possible, i.e:
col-xs-3 therefore implies col-sm-3, col-md-3, and col-lg-3
So if you want something on your webpage to stay consistent for all devices, then you can declare the smallest column size (xs) and have that take care of all small, medium, and large screen sizes. An example of this is below:
