Cannot embed large size cover image(s) for FLAC

When writing tags for FLAC files, the program simily fails if the cover image file that is bigger than about 20mb. I have been wrestling with the cover image which happens to be 35.6mb (PNG file), and the program tells me it cannot write the tag. I reduced the size to 24mb (JPG file) and it still fails to write the tag. Is this limitation of FLAC tag structure? ....My guess is that not many people are that insane enough to put ultra high quality cover art files, but it would be great if this …

It looks to me as though some other program wrote an invalid FLAC tag.
