`urllib.urlretrieve` was using the correct extension in most cases -- I think when the URL ended with .jpg -- but not in every case. This was leading to files named just "cover" and not "cover.jpg" or something else sensible. In particular, proxied URLs don't have .jpg extensions. This generates the filename manually so the source image always has an extension.

FetchArt Plugin
|
|
===============
|
|
|
|
The ``fetchart`` plugin retrieves album art images from various sources on the
|
|
Web and stores them as image files.
|
|
|
|
|
|
Fetching Album Art During Import
|
|
--------------------------------
|
|
|
|
To automatically get album art for every album you import, just enable the
|
|
plugin by putting ``fetchart`` on your config file's ``plugins`` line (see
|
|
:doc:`/plugins/index`).
|
|
|
|
By default, beets stores album art image files alongside the music files for an
|
|
album in a file called ``cover.jpg``. To customize the name of this file, use
|
|
the :ref:`art-filename` config option.
|
|
|
|
To disable automatic art downloading, just put this in your configuration
|
|
file::
|
|
|
|
[fetchart]
|
|
autofetch: no
|
|
|
|
Manually Fetching Album Art
|
|
---------------------------
|
|
|
|
Use the ``fetchart`` command to download album art after albums have already
|
|
been imported::
|
|
|
|
$ beet fetchart [-f] [query]
|
|
|
|
By default, the command will only look for album art when the album doesn't
|
|
already have it; the ``-f`` or ``--force`` switch makes it search for art
|
|
regardless. If you specify a query, only matching albums will be processed;
|
|
otherwise, the command processes every album in your library.
|
|
|
|
Image Resizing
|
|
--------------
|
|
|
|
A maximum image width can be configured as ``maxwidth`` to downscale fetched
|
|
images if they are too big. The resize operation reduces image width to
|
|
``maxwidth`` pixels. The height is recomputed so that the aspect ratio is
|
|
preserved.
|
|
|
|
Beets can resize images using `PIL`_, `ImageMagick`_, or a server-side resizing
|
|
proxy. If either PIL or ImageMagick is installed, beets will use those;
|
|
otherwise, it falls back to the resizing proxy. If the resizing proxy is used,
|
|
no resizing is performed for album art found on the filesystem---only downloaded
|
|
art is resized. Server-side resizing can also be slower than local resizing, so
|
|
consider installing one of the two backends for better performance.

Album Art Sources
|
|
-----------------
|
|
|
|
Currently, this plugin searches for art in the local filesystem as well as on
|
|
the Cover Art Archive, Amazon, and AlbumArt.org (in that order).
|
|
|
|
When looking for local album art, beets checks for image files located in the
|
|
same folder as the music files you're importing. If you have an image file
|
|
called "cover," "front," "art," "album," for "folder" alongside your music,
|
|
beets will treat it as album art and skip searching any online databases.
|
|
|
|
When you choose to apply changes during an import, beets searches all sources
|
|
for album art. For "as-is" imports (and non-autotagged imports using the ``-A``
|
|
flag), beets only looks for art on the local filesystem.
|
|
|
|
Embedding Album Art
|
|
-------------------
|
|
|
|
This plugin fetches album art but does not embed images into files' tags. To do
|
|
that, use the :doc:`/plugins/embedart`. (You'll want to have both plugins
|
|
enabled.)
