I installed the Rounded Borders to my Default theme and left the provided defaults. But I don’t understand how this applies.
Does this work on a per‑uploaded‑image basis, site‑wide going forward, or site‑wide for everything?
Do I just need to upload and JPG and let it do its thing? Do I get some choices at that juncture? I am on a production site so I don’t like to experiment too much. Puzzled. TIA.
