Gallery component not 100% width in all browser sizes

[rothenburycam]

Expected behaviour

Image thumbnails in gallery component should re-size/re-organise to take up 100% of browser window at all browser widths.

Actual behaviour

Image thumbnails do no re-organise to occupy 100% of window in all browser widths. Leaves a column of white space to the right-hand side. Not sure if this is possible to fix. Does not affect appear to affect normal media query sizes.

Steps to reproduce

Re-size browser window to different widths.

This is particularly noticeable when the images are all the same width.
