This is wrong. MasterLinks is an ib_stringlist. Each entry is a
string of the form (using your example)
ANIMAL.ANIMALID=ANIMALPHOTO.ANIMALPHOTOANIMALID
i.e. detail link on the left, and an equals sign with no spaces.

You can't assign MasterLinks in code using a Delphi assignment
operator. You must use
aDataset.MasterLinks.Add('ANIMAL.ANIMALID=ANIMALPHOTO.ANIMALPHOTOANIMALID');

I suspect IBO is somehow parsing something out of your code but, at
best, it will have the relationship reversed because it's being told
that ANIMALPHOTO is the detail side.
