Finder not displaying all files in remote directory

I've exported pictures from iPhoto on my iMac to a shared directory on my mac mini. When I access that directory from my iMac, I can see some but not all of the pictures. I know the pictures exported properly because I can see them all from the mac mini. I can open up a terminal window on my iMac and see all of the files; I can also open those files from the terminal.

I'm running OSX 10.9.4 on both computers, with the mac mini also running OSX Server. I've placed a screen grab below from my iMac of what Finder sees vs what I can see from the terminal.

Why isn't Finder displaying all of my files?
