Andra Waagmeeter has been improving his Tarsier tool. Tarsier finds images of organisms that carry an open license (CC0, CC-BY, CC-BY-SA) you can reuse — from GBIF occurrences and from the taxonomic literature (Plazi figures via the Biodiversity Literature Repository on Zenodo). It judges each image on its own license, flags whether a copy is already on Wikimedia Commons, and where the license is compatible links straight to a pre-filled Commons upload (a Wikimedia account is required). Search by scientific name, or by a common name — common names are resolved to a taxon via Wikidata.
Warning: Currently this link in my chrome browser displays a bright red warning about an unsafe link. Andra has said this warning is there as he needs to request a review as he was hosting multiple platforms under that main domain. He’s going to sort it in the near future.
