[GeoNetwork-users] Controlling thumbnails (2.8)

When I upload a thumbnail regardless of whether I select the options for creating a small or large size or if I attempt to leave the resizing off, the XSL for metadata-tab-utils classifies it as an unknown type and resizes. This is somewhat okay as long as I comment out the part of that code that forces a square 180x180px image (I changed it to just resize to the width), but I'd really like it to behave. Commenting that portion of the XSL means my images don't display at all.

I've double checked the XML using the editor and the fileType is appropriate (jpg or png).

Any thoughts on where to check next or a workaround?
