Unable to set image via URL when using tag.

[sirnoob-1]

When editing files with EYED3 tag and attempting to set a image for the MP3 file it doesn't do anything, no errors and no result.
audiofile.tag.images.set(type_ = 3, img_data = None, mime_type = None, description = "Album Artwork", img_url = searchResult['art'])
(Where audiofile = an eyed3 loaded audio file)

Here is the line of code I'm using, URL is a valid image.

Thanks
