> FLAC has a limitation of ~16MB because the length field of the metadata block can only hold numbers up to 24bit. I'm moving this to #bug-reports:no-bugs

and since Mp3tag v3.18a there should be an extended error message about this fact:

> [@Missing error message if cover file ist too big](https://community.mp3tag.de/t/missing-error-message-if-cover-file-ist-too-big/58598/5):

> I've extended the error message with [Mp3tag v3.18a](https://community.mp3tag.de/t/455). Thanks for pointing!
