Admin with Thumbnail Ref

Hi,
Would like the ability to add a thumbnail image reference under categories. I use the corporate theme which makes use of 1 image assoicated with each blog see http://hexotest.computerlab.io/archives/
Thanks,
John

The issue requests thumbnail image references for categories, with an example of a corporate theme using one image per blog. No files, tests, or entry points are identified; first locate the category-management and theme-facing code, then confirm the expected stored reference and rendering behavior. Done means categories can hold and expose the requested thumbnail reference.
