I will try and describe this as best I can, can't remember ever having this problem before.
I have added some files to Calibre that had 'home made' covers. I have been through each file and changed the metadata to show the original book cover which it does nicely in Calibre, however, still in Calibre, if I open the individual book file to read, the old original home made cover is still there and has not been replaced by the one showing in Calibre if you see what I mean
What am I missing, I assume I am just having yet another senior moment
