We are changing a real estate site, and want the home page to open with image A. Image A (we hope) will then rotate to any one of several possible random images of properties for sale. The second image will then stay unchanged until the user reloads, at which point the cycle should start again, loading Image A then another random image. And the second image (ideally) will be clickable.
My coder knows how to rotate images in PHP (although PHP is new to him). What we don't know how to do - or if it is possible - is to always bring up one image, then a second random image. Is this possible in PHP, or do we need to try another approach?
