Fixes #862, Fixes #863

Removes unused inline style
Fixes scrolling issues
Fixes images being cut-off at the bottom
Fix indentation
Fix issues with styling not being applied after adding an image

The active class was not being applied to indicators properly
Disable the image carousel next/prev when there is 1 image or less

Bootstrap Carousel would not work properly with only one image, and could
not recover after adding more, so I disabled the controls until there are
at least 2 images
