Is there a command line tool that will do this (such as tag)? I'm trying to make this part of a process that requires very little user interaction.
I'm not aware of any CLI tools that support the APIC frame directly. Several ID3 libraries do support it though, you could write a script using Perl or a program using C or something to use one of these libraries and make a CLI tool to do it, however. Shouldn't be too hard to do.
