Linking OneDrive picture folder with picture app

Hi there. I have a personal office 365. Which works only on one pc (we only used one) but I didn't thought of the complications whit multiple live id's. It my wifes live id, that are hooked up with the onedrive, so she stores all the pictures. I would like access to those through the pictures app, but I can only see it's possible to link to my onedrive account. I'm not interest in having them stored locally, since they take to much space.
Can I link her picture folder to my picture app?
