Photo Tiling Margin?

I am trying to make a “rope” section divider by using the photo tile in a single row by using a short section of the rope to repeat and look like a long rope. But when I tile anything there seems to be a 1 px margin between the image so it doesn’t quite touch and looks wrong. Is there a way to make the image tile touch end to end without a space or a way to make the space tighter?? Thanks in advance!
