Default [Q] Unable to see photos transferred from Galaxy Nexus into Nexus 5 in Gallery

Hi, I am not sure if this is an old issue, but I tried to search in XDA and Google but could not find anyone experiencing the same issue as me.

I have used Galaxy Nexus and Galaxy S3, and transferring photos between them will still allow me to view the photos in Gallery. But recently when I got the Nexus 5, I transferred some photos over from Galaxy Nexus into the exact same folder where the photos will be saved from the camera, but it does not show up in the Gallery.

I was wondering if it is because the Gallery detects that the photo is not taken from the device, and therefore will not show in the Gallery?

Appreciate your help. Thanks in advance!
