Hr more check details

Hi,

There were a number of little formatting errors on this screen (for details see 97d3890), and there were a few particular details missing from the file details list (see f208f16).

Also added a lightbox preview for the image.  We have the ability to make arbitrary width thumbnails of the images, so we may as well use it! 

A remaining issue: there's no way to know if the 'save' button does anything. An obvious way to fix that is to disable the button after it saves or when the form is unchanged.  That's the way it's done in other parts of the job upload workflow.
