Two things i must add to the previous messages i've sent. First of all, to 
find out more on "osdownloader," go to this link: 
http://www.nebulais.com/osdownloader/index.html

Second if you wish to download a package which better explains the whole 
concept, you can download it at the bottom of the demo page. Or go to this 
url: http://www.nebulais.com/osdownloader/download.html

I personally think this is a more ideal way of opening the save as dialog, 
but it might generate a few errors if you have a window/program hogging 
bandwidth, or if you are a mac user who does not have .htaccess control 
turned on. I think it is more conveniant for the user as well(he doesn't 
have to decompress or change the extention).
