Came across an interesting optical effect... Take a close look at the horse in photo no. 5 on the page

Now, there is obviously a mesh screen between horse and camera, so why the fringes ?
Anyone able to volunteer a cogent optical explanation ? PS I know, but curious to see if other IIS members can figure it out.
