• Replace: The specified album art replaces any existing album art.

• Prepend: The specified album art is placed in front of any existing album art.

• Fallback: If the original input file contains artwork, Elastic Transcoder uses that artwork for the output. If the original input does not contain artwork, Elastic Transcoder uses the specified album art file.
