Good evening! I am hacking together a web page for our church, and the pastor wanted to have an image scrolling similar to this site (Sidley Austin LLP - Home). I have been doing some searches, and can see other sites that are using a similar script. I haven’t been able to find the creator of the script to see if it is a pay script, or if it is a free to use script.

Does anyone know of a script that is free and looks similar?

Possibly Continuous Image Marquee is similar enough for what you want to do.
