I'm trying to make the end-image in flash, so you choose a gif image in the display but the output in your postbit is a flash image with a three day timer. After chosing a pet, the flash is displayed and the timer counts down to zero and if it is zero the pet dies and turns upside down, legs in the air. When a pet-user in those 3 days click on a small button 'feed pet' the timer is reset and is counting again on it's starttime.
Now, so far this is theorie but i can do it if i have a good timerscript. I let you know.
