Plotting a vector field over an image

Hello all,

I'm attempting to overlay a vector field over an image. I have a vector
for every pixel. I'd like to be able to be able to only plot a subset of
those vectors. For example, only plot every fifth vector in its place.

I've attached code that plots every vector. Any suggestions on how to
modify it to plot every Nth vector?
