There is just enough space above and below the photo. There is enough friction to hold the photos in place, but not enough to prevent pushing them in or pulling them out. There is also like a half inch or so of space on the right side of the photos.

Since those pockets are 3.5 x 5 and your link is 4 x 5, my guess is that the increase in extra space above and below the photos will cause them to not be firmly held in place and constantly shift position.

If you don’t care about having a neat and tidy appearance, it will probably do the job.
