WD My Passport - MAC - Locked Photos - Have password

I have a 1TB WD My Passport external drive (had quite a long time!) - which I used to back up a great deal of photos

When using my Mac, I can plug it in, and the drive is recognised.

I can see the files, and look at the photos, however the drive is locked and so are all the individual photos.

I can unlock the drive, but am unable to unlock the photos - which means I cannot edit them, move or remove them

HOWEVER, when I plug the drive into an old windows laptop, I have free access to all.

How can I unlock so I can use on my Mac please.

Total oldie numpty here.

TIA
