After several hours learning of eyeD3, googling and experimenting with file cover, I think, I have a solution for you.
You need to follow these rules:
- use ID3v2.3 (not v2.4 as by default in eyeD3);
- add right description for cover image (word
cover
);
- pass image as binary;
I'll give you an example of code, which works fine on my Windows 10 (should works on other platforms as well):
import eyed3
import urllib.request
audiofile = eyed3.load("D:\\tmp\\tmp_mp3\\track_example.mp3")
audiofile.initTag(version=(2, 3, 0)) # version is important
# Other data for demonstration purpose only (from docs)
audiofile.tag.artist = "Token Entry"
audiofile.tag.album = "Free For All Comp LP"
audiofile.tag.album_artist = "Various Artists"
audiofile.tag.title = "The Edge"
# Read image from local file (for demonstration and future readers)
with open("D:\\tmp\\tmp_covers\\cover_2021-03-13.jpg", "rb") as image_file:
imagedata = image_file.read()
audiofile.tag.images.set(3, imagedata, "image/jpeg", u"cover")
audiofile.tag.save()
# Get image from the Internet
response = urllib.request.urlopen("https://example.com/your-picture-here.jpg")
imagedata = response.read()
audiofile.tag.images.set(3, imagedata, "image/jpeg", u"cover")
audiofile.tag.save()
