thank you very much for your guide. but the point is i want to have a crosshair that point to the place (coordinate) that i have enter in a text box. here is the code my code:

% opening the image by pushing button 
 FileName=uigetfile(*.jpg);
 figure
 imshow(Filename);
%calling the edit text boxes for entering the coordinates    
%function edit1_Callback(hObject, eventdata, handles)
%making a oush button

now i want when i push another button a crosshair jumps to the desired coordinate. thank you very much
