I want to beable to create a Flash movie with a single picture on the 'wall' in a room. When a person clicks onto this picture a 'pop-up' window will open up displaying a number of new picture images (which are linked to a database). When they click onto a picture they like, it will download to a specified folder on they hard-drive, and replace the current picture on the 'wall'.

What I need to know is:
1) What language/database should I be using to display this 'pop-up' window with new images? XML/PHP/mysql?

2) Is there anyway I am able to open up this 'pop-up' window without the usual Microsoft branding i.e I don't want people to know that they are having the information displayed in a Microsoft Internet Explorer browser page.
