Best way to add Album Art to Existing Library?

[makitamark]

I have a rather large (by my standards) music library all ripped in flac and stored on a NAS drive.
For whatever reason some Album art is missing in perhaps 5% of my Library.
I have found I can 'edit' the ID-Tag on each track individually and locate the missing Artwork and 'insert' it into the ID-Tag.
However, every time I add the Artwork Dbpoweramp goes into a 'not responding' state and then after 30sec or so it comes back and the new Artwork has been added, but ONLY for that One Track.
Is there a better way to do this that will apply the Artwork to ALL tracks of the Album?
Is there a reason DbPoweramp 'crashes' when afixing Artwork?
First Post, Please be Kind....
