I have a bunch of push button where the user can put pictures on but how do I check if the push button has an image on it or not? Below is the code I thought would work but wouldn't. Any help is greatly appreciated.
if (handles.pushbutton1,'cdata',[]) || (handles.pushbutton2,'cdata',[])
msgbox('There are still empty tiles')
end

You need to use get and isequal:
if isequal(get(handles.pushbutton1,'cdata'),[]) || isequal(get(handles.pushbutton2,'cdata'),[])
%...
end
