Hi Ben,
That works.  The only problem is that the grid is centred in the middle so that the edge of the photograph has half squares all around it.  I need the grid to start at the edges so that there are 10 full squares along the width and the same along the height.  Is there any way to adjust the plugin to mean that the edges of squares start at each edge?

Many thanks
Sarah
