this is the code

   true
    %point location
row=find(sum(img8,2)==0,1,'last')+1;
col=find(img8(row,:)~=0);
row=row(ones(size(col)));
Points=[row(:) col(:)];
imshow(img8);
title('Highest Point Location')

plot(Points(:,2),Points(:,1),'rp','MarkerSize',10)

Do you mean you want a label near the plotted point? You could use the text command, using your Points variable to place it:

text(Points(1,2),Points(1,1),['This is (',num2str(Points(1,2)),',',num2str(Points(1,1)),')'])

You would then need to loop over your points.
