@vn2009 - thanks, I looked into buying the source code. I am just not sure it is worth it considering what I can do with it. When I add the rest of the gigapixel photos perhaps I will do so.
That is an impressive site you have. How did you do the aerial?
in my opinion if you cannot modify the code yourself or do not mind paying more to add the needed code to include multiple spots the exsisting souce is not worth the cost just to change 2 icons. thankfully i could afford the cost to have it further modified.
the aerial = the hardway. a real helicopter with a self made retractable boom that was lowered under the chopper then i had to manually spin it every 60° and take 6 shots while we hovered.
