Images not being saved in MP3 file

I have been using the Actions/Actions (Quick)/Import Cover from file but the image only appears when the MP3 file is shown in MP3TAG and nowhere else like File Explorer or on my Android phone.

Any ideas about what I'm doing wrong?

Thanks.
Glenn.

No, but see e.g. here

No help at all :disappointed_relieved:
Maybe it's got something to do with the tag version?

Don't know - which have you got?
What kind of files are we talking about?
What kind of tags (ID3, APE) are in the files?
Are the files ok?
Are the pictures not too big?

MP3 files. Just used MP3 Book Helper to write ID3 tags v2.3 and it has worked fine. Windows Explorer is now showing the cover art.
