Fixes Issue #19

I'm not sure this is necessary, since this only affects the web portal, see #19 (comment)

Effectively as it stands not all 233 unique images can be viewed. Perhaps if they were renamed to move 2x, 3x, etc to the front of the filename, that would fix it. In any case necessary and optimal are not always one in the same.

The view is only blocked when viewing Github through the web interface. You still get full access to all of the files after running git clone. Is it vital that we can see each of the files through the web interface? That doesn't seem like a high priority to me...
