ButtonDownFcn for axes not working.

Hi everyone, i have two axes, axes1 and axes2. axes1 contains an image, and axes2 is empty. I want the axes1 image to get copied on axes2, when i click axes1 image body. I tried the following:
set(handles.axes1,'ButtonDownFcn',{@copyImg,img});
function copyImg(img)
axes(handles.axes2);
imshow(img);
end
But no response when I click the image. What am I doing wrong ? Any help would be appreciated. Thanks in advance !

The image is absorbing the clicks. You need to turn off its Hittest property if you are using R2014a or earlier, and for R2014b or later, turn off its PickableParts property.

No - you don't turn the hittest off for the axes, you turn it off for the image. Get the handle to the image from imshow():
hImage = imshow(.....
set(hImage, 'hittest', 'off');
or something like that. (I didn't test it).
Alternatively you'd have to set up a callback for the image itself, and have the image callback do what you're having the axes callback do now, but that's a lot less straightforward.
