Speed Test

Hi guys

My client emailed me this morning w/ an interesting challenge. If you have any idea on how I might accomplish this ... perhaps w/ javascript(?) ... I'd be most grateful!

Here's his message:

"Carl, I have created a series of images that the user needs to identify patterns as a speed test. What I would like to do is flash an image on the screen and he has four choices at the bottom. He selects his best choice and the next image is flashed. He is graded for both time and speed."

Might this be possible? Or similar?

Thanks a ton!

Carl
