Embedding album art deletes all tags??

[jangjang]

EDIT: Turns out the problem was that the album art was too big. This is my first time encountering this problem so I don't know much but, I'm guessing that embedding a picture with a file size too high will break the files.
I read online that Flac supports up to 16mb max and my artwork was well below that but I guess it was still too big.

So I was organizing my music today when I discovered something really strange. I was trying to change the album artwork of one of my albums since it was a very low resolution image. I downloaded a high resolution version of the album cover and tried to embed the artwork. However, when I do this, it for some reason deletes all tag information.

For example, the tags are all normal and look right in Musicbee, but when looking at the files in the file explorer, the tags are all empty and won't let me edit them. I opened the files in Poweramp and the tag information was all missing as well.

If I do not embed the artwork, everything is fine. I do not know if this is a limitation or a bug but I just wanted to ask in case anyone else has come across this problem.

I can provide screenshots and files at request.

Have you used the Tag Inspector to see if the tags are really there?

I deleted the album and re-added it to my library and this time tried embedding the same artwork, but smaller resolution and file size. And well, everything works and the tags are all there. I'm guessing the artwork I used was too big and it broke the files?

Edit: also yes the tags are there in tag inspector

It's more likely that there was an issue with the particular artwork file you used. How big was it? You say everything still looked fine in MusicBee, but did you answer phred's question about the specific file you had a problem with? How did you restore it after adding the artwork that caused the problem?

The artwork was 2500x2500 and 8.7mb. I restored it by deleting the album from my library and copying it back in. All my music is in a separate folder and I copy them into a folder specifically managed by Musicbee, so in case anything happens, I always have the original files.

Later I also found another album with the same problem, and it also had a ridiculously large album artwork. (22mb)

I fixed both by embedding a smaller artwork. (I didn't have to delete and copy the album, all I had to do was embed another artwork)

Since everything is fixed now I am reluctant to go and change the artwork again but if you want me to test it, I can.

Thanks for the replies.

I've had problems with large album art and syncing, but never just within MusicBee. If you still have one of the files with the large artwork I'd be curious to take a look at it.

For FLAC files, MB uses the official flac API to read and save tags, so i guess its possible there is some size limitation for flac files. I would also be interested to have a look at one of the files, along with the large artwork file you were trying to embedd

Here are the artworks in question:

I tried uploading to imgur but one of the files were too big.

I can also link the albums if you think they were the problem, but I tested and it happens on all my albums.

Let me know if I did anything wrong. Thanks!

For FLAC files, MB uses the official flac API to read and save tags, so i guess its possible there is some size limitation for flac files.

According to the developer of Mp3tag, "FLAC has a (picture size) limitation of ~16MB because the length field of the metadata block can only hold numbers up to 24bit."

For the very large picture, i agree it doesnt save. Unfortunately the flac API doesnt return an errors so there is no error MB can look for. However for me, its not affecting any of the other tags.
For the second smaller picture i have no issues saving the picture or tags
