I am using an already made php realestate script but it has some flaws. The script automatically resizes images for the thumbnails but doesnt appear to do so for the main images, it allows any size of image to be displayed (way too big also). A;so, is there a way to dissallow any drop down search box information being taken into account on search engine crawls? It will totally stuff my website optimisation as it shows every single price, state, number of bedrooms etc etc when I run a search test. Thanks
