Embedded album art dimensions (height, width)

I'm trying to fix my music library and make all mp3 parameters unifyed. Files in my collection has different embedded album art. And I want to see that difference quickly.

By addind fields such as %_covers% and %_cover_size% I can get some information about it.
But... is it possible to get height and width of that embedded pictures?

Thanks in advance.

This is currently not possible.
