You need to access the appropriate frame or atom in your tag.

Some aproximate code to get you started:

For ID3:

for ( auto it : v2Tag->frameList("APIC") ) {
    AttachedPictureFrame *apic = dynamic_cast<AttachedPictureFrame *>(it);
    if ( apic ) {
	// use apic->picture().data() of apic->picture().size() to create an image in your \
app framework  }
}


For mp4:

CoverArtList coverArtList = tag->itemListMap()["covr"].toCoverArtList();
for ( auto it : coverArtList ) {
    CoverArt pic = static_cast<CoverArt >(it);
    // use pic->data().data() of pic.data().size() to create an image in your app \
framework }

Hope this helps,

patrick
