Hi,

I have gotten a better technique for making photomaps using svg and inkscape,
it is really easy to use and you can color the imagemap how you want.

SVG Photomapping with inkscape

With Inkscape you can make the imagemaps much much easier,

just load them in and create a box over the building,

right click (create link) fill in the href with the osm id and target (new)

then you are done. Make sure you fix the image to be on a public server.

here is an example :
