+A Note About Fields
+-------------------
+
+If you wish to store embedded cover artwork metadata in the file, you must 
+use the field ``images``. This is a special field and is not shown by 
+issuing the command ``beet fields``.
+
+For example::
+
+    zero:
+        keep_fields: title artist album year track genre images
+        
+This will result in the following metadata field in an MP3 file::
+
+    APIC (Attached picture): ()[, 3]: image/jpeg, 88742 bytes
