You have one image with the ID of "house". It looks like your script is working on that ID. I don't know that script, but it seems if you changed the image to be CLASS=house instead of ID=house, and then have multiple images with CLASS=house, and change the script to work with '.house' instead of '#house' it would work on all images with that class.
