Choose an artwork owner
Music artwork can come from several places, and the most attractive picture is not necessarily the one the library selects. Jellyfin gives supplied external artwork priority and otherwise can use the first track containing embedded art. Album cover.jpg and artist-root folder.jpg are documented placements to distinguish. Decide whether your small collection should use intentionally supplied local art or rely on another metadata workflow before replacing images throughout the library.
Begin with one album and one artist for which you have permission to use the images. Record the image source, permitted use, current filename, intended scope and whether the audio files also contain covers. This is especially useful for self-produced recordings whose early and final artwork may both exist. An image visible in a folder does not by itself prove that it has the intended role in the server.
Inspect competing inputs before making changes
Look for multiple cover candidates beside the tracks and for embedded art in the audio. Compare their dimensions and content using ordinary image or tag inspection tools you trust. Avoid deleting alternatives until you understand which one the library currently presents. A saved screenshot of the album and the local input inventory makes a later comparison more precise.
Apply only a documented filename and placement for the desired artwork type. Do not infer an artist-level image rule from an album-cover rule, or assume that adding a larger image automatically overrides every competing source. If the documentation for your installed version and media type is unclear, keep the change to a sample rather than extending an uncertain convention across the entire collection.
Review identity, image and client separately
After the appropriate metadata update, confirm that the album identity is still correct and that the intended picture appears. These are separate questions. A good cover attached to the wrong release is not a successful artwork update, and a correctly grouped album can still show an unintended embedded image.
Then check the client where the image matters. Record the client version and the date of review instead of promising a universal appearance. For an authored example, a rehearsal-room recording might use a square cover for album browsing while the artist page needs a different composition. Inspecting each location prevents a single crop from becoming the assumed answer for every screen.
Keep a reversible art policy
Retain the original image and its provenance record, including any restrictions on redistribution. Do not copy commercial album art from an arbitrary search result into a public asset collection merely because it is small. Library organisation and image rights are independent decisions, and Jellyfin does not supply a blanket reuse licence for images you find online.
Once the sample is satisfactory, document the chosen convention and the update operation used. Expand gradually and keep exceptions explicit. Recheck representative album and artist pages after changing metadata providers or server versions. The finished result is an explainable artwork choice with known inputs, not a promise that a filename alone will make every client display identical images.
Questions answered
Should I remove every embedded cover when I add a folder image?
Do not make a collection-wide deletion without checking the documented precedence and a reversible sample. Preserve the original files and artwork inventory.
Does an album cover also prove the artist image is correct?
No. Review each artwork role and the relevant page separately.
