Adding "album art" to MP3s ...

hoaf has asked for the wisdom of the Perl Monks concerning the following question:

... is painful.

Since I'm so cheap (and bored at work, to be honest), I've taken in upon myself to write a perl mp3 parser, tagger, and calaloger (sp?).

Extracting and modifying the text tags for the MP3's is pretty easy using MP3::Tag. Heck, I can even successfully extract the images from the "APIC" tag when I create a nice, pretty web page.

Thing is, I really want to be able to replace or add a new image to certain MP3s, but I can't for the life of me figure out HOW to a) extract the relevant binary information from my album art (jpg and png format) and b) shoehorn said information into the appropriate data slot (APIC) in the MP3 ID3v2 tag.

So ... any ideas on where to look and/or how to proceed?

Thanks a bunch!

UPDATE: Thanks for the html(ish) help, McDarren!

    #!/usr/bin/perl use warnings; use strict; use MP3::Tag; my $artfile = 'barred-spiral-NGC1512.jpg'; my $art; { local $/=undef; open my $jpg,'<', $artfile or die "Couldn't open file: $!"; binmode $jpg; $art = <$jpg>; close $jpg; } my $mp3 = MP3::Tag->new('Andrew_Ford__Cygnus_X1_Trawler.mp3'); $mp3->get_tags(); $mp3->{ID3v2}->change_frame("APIC", chr(0x0), 'image/jpeg', chr(0x0), +'Cover Art', $art); $mp3->update_tags(); $mp3->close();
