If you want to clear the whole canvas instance of all items on it, use:
canvas.delete('all')

i don't want to delete the whole things. i just want the image to be deleted...
can you tell be how i can do it????

Then you have to give your image object a name ...
img1 = canvas.create_image(200, 250, image=photo)
... and delete that on specifically...
canvas.delete(img1)
