Try: MovPic Config -> "Importer Settings" tab -> "Artwork" section -> edit cover entry -> add %filename%.png| to the start of existing input. And I can not remember if "Data Sources" -> 'manually manage' -> "Cover Art Data Sources" button -> "Local Data" source needs to be positioned first, or if that was for artwork inside the thumbs folder only. Worth to try as well if the above fails I guess.
