Managing how windows open


I have a bunch of photos of historical documents indexed in a folder. I like to open the photo files with the keyboard shortcut (command-O) and then use the keyboard shortcut to open a linked annotation.

What I would like to do is have the photos open up in the top left hand corner of the screen, and the annotation windows open up positioned in the top right hand corner.

For some reason, the photos open up towards the center of the screen, but the annotation windows open in the top right hand corner.

When I move the photo window to the place I want it, close out, and re-open, it opens to the desired location. However, when I move on to the next photo, I have the same problem as before. How can I fix this?
