I was searching around for scrolling Marquee and found how to add images that
change every 3 seconds and for the life of me I can't find where it is now.
Any idea?

I am not sure how scrolling marquees relates to revolving pictures. They are
somewhat different.

Anyway, I replied to a similar query recently so, hoping it answers your
query, below is the code I posted.

This code actually use images from http://javascript.internet.com, so you
don't have to change anything to see it working.
Changes you would need to make:
1. var interval (this is in milliseconds) - you may want 3000
2. var random_display
Set to 0 to display images in the order you specified them.
Set to 1 to display images in random order.
3. The image-list entries.
e.g. image_list[image_index++] = new
imageItem("http://javascript.internet.com/img/image-cycler/01.jpg");
Alter the contents of the brackets to your images.
You can add as many as you like.
4. The width and height of the image.
It is set to 120*90, so this will only corectly display images with these
proportions.
To display a larger image, alter these parameters. If you don't know the
ratio of width to height, specify only one of width and height.
