Can anyone help?
I want to make a Flash in which appears a map and when you mouse over some areas appears real picture of the site through which it passes (eg a school level and by passing the mouse over the photo appears courtyard patio).
I need urgent help.
if this is something you need to do - urgently - you'll need to learn about rollovers and rollouts, using either addChild of Library items, toggling visibility or alpha of items already on the stage, or loading in/unloading external swfs into a Loader.
those would be the most popular ways of accomplishing this. there are easily searchable tutorials and discussions on all those methods.
if you have specific questions that we can answer, please let us know.
