Item-level Image Display Enhancements

[chrisrlc]

From stakeholders:

Aesthetics of item pages are clunky: We would like to be able to change the size of an image to make more strategic use of white space on an item level page, rather than being restricted to the default size of a bounding box. And we would like all text to be justified left.

Make bounding boxes responsive to size of images: If an image is particularly large (either horizontally or vertically), the boudning box scrunches it while leaving a lot of unused white space on an item page. We also do not like how the bounding box always displays grey borders around images. We would like the option to make the box transparent.
