Are these pictures of the inside or the outside of your house?
If it's the outside then it's probably legal. Any photo taken from a public place is legal as far as I know. Could the photo have been taken from the public road?
If it's the inside then it's trickier. The law likely has nothing to say on this, and the Data Protection laws don't seem to apply to a persons property. I understand that you wouldn't want photos of the interior of your house up, but what specific law has been broken? Has a law been broken? What if it's in the T&Cs that you signed up for that photos may be taken?
As far as the driveway people go, they haven't committted any offence either (imo), and only would if they fraudently passed off someones elses work as their own. Displaying the pictures on a website wouldn't be illegal in my view, if the photos were taken from a public place.
