Figure overlaying help

Hi i have the following code, i was wondering if it is even possible that when the user opens a graph, is it possible to overlay the images for comparison? i have very little knowlage of matlab so sorry if this seems a rather simple question :).. thanks for any help in advance :)

%reset the while_condit condition to 1 while_condit = 1;

%repeat code within until answer is no while while_condit < 2;

%asks the user if they want to open a new graph answer = input('do you want to input another graph for comparison? [yes, no] only \n');

%computes the answer to check wether a new graph is to be opened while_condit = while_condit + answer ;

%opens matlabs GUI interface for the user to specify which graph they want %to open if while_condit == 1 uigetfile('.fig') else end

figure; i1=imshow(k1);

hold on

i2=imshow(k2);alpha(i2,.4);

%will fade the i2 image.
