Hello

I have a timer attached to an update panel. In one instance I want to perform a blink type function on an image:
example
if image1.imageurl = "red.jpg" then imageurl ="black.jpg" esle image1.imageurl = "red.jpg"

my problem is that the first time the timer executes it changes the image to black.jpg, but each time the timer runs image1.imageurl is always equal to red.jpg even though it is visually black.jpg. What am I doing wrong?
