Simple preloader question

Hi, I want to make a preloader that simply flashes an image on the screen. once the movie is loaded i want the image to continue flashing for another 30 frames. I searched long and far but all i can find are tuts dealing with percentages, progress, etc… Thanks in advance guys.

maybe you can do this: make something with percentages, so they can see how for it is and set the picture also in the preloader. At the end, you make a gotoandplay() to the frame you want

good lcuk
