Rollover/button.. thingy

Hello everyone.

I want to creat a flash document where I can put my cursor over one image (Image1) and a second image (Image 2) pops up. But I dont want this to be your average image rollover. When my cursor leaves Image1, I would like Image2 to still be up.

Is this possable? and if so.... can you tell me how to do it? 
          Thanx. [COLOR=DarkOrange]Dan[/COLOR]
