What value will get stored in handles.axes if image is present and if the image is not present? I want check the condition whether image is present or not, and i implemented this
if handles.axes1==0
msgbox('Please insert image. . .', 'Error. . .');
end
but this is not working, please suggest me the best way of doing this.

You could try
if ~ishandle(handles.axes1)
However, if the axes exists but does not contain an image, the axes will still be a handle. But you can test
if isempty(findobj(handles.axes1, 'type', 'image'))
to see whether the axes contains an image
