Estate Agents and Building Agents: The last people on the planet to realise you can put BIG pictures on the internet.
Seriously guys: No one's going to buy or rent your property because you put up tiny photos that made it look like it might be nice/look big. They'll come and see it first and then you've utterly wasted everyone's time when they realise it's mouse-hole/shit-hole, haven't you?
