I am trying to overlap two pictures one of them is in .jpg file and other is contour plot from MATlab. I want to overlap on one an other to compare the contour lines. Does any body know what code can be or any manual way?

You can use hold to superimpose contour lines on an image. Here's an example:
% Get an image from a jpg file
img = imread('street1.jpg');
% display it
imshow(img);
% superimpose a contour map (in this case of the image brightness)
hold on;
contour(rgb2gray(img), 5);
hold off;

What do you want to do with the rows that have missing measurements? Ignore them? Interpolate them?

There is a function for that. It's called imfuse().
