Sometimes when you add photos to your album the images tend to show up with a handful of thumbnails that are already in album. I stumbled across this tip while trying to highlight a single photo on my timeline, and still keep that photo neat and organized in the album that it belongs in.
Add the photo to the album..
Select the photo and click share..post/share it to your timeline..
Click the edit/remove button, and go down to Reposition photo..
You can then grab image and position up or down to view a nice image and keep the photo organized within your albums
You have then created a nice large photo displayed on your timeline to be the focal point of an album at anytime.
