You can scale (I mean resize, not abseil :-) ) the height of the building by using the ratio of the side of the building in the photo. For example:- You have a photo with the side of the building being 2 inches high by 6 inches wide. If you happen to know that the side of the building is 60ft long, then the side building is 20 feet high. Note: You do not need to know how far you were away from the building to do this. For 3:00am I think this makes sense. Regards George ------------------------------------------------------------------------- Using Tomcat but need to do more? Need to support web services, security?
