Plotting the Beam Spot centroid of multiple images

I have multiple .bmp images of a laser beam spot. I am trying to calculate and find the beam centroid of each image and plot the centX and centY value of each image all on the same plot.

Can you attach the code? What problems are facing? What is your question?
