Flexi Slideshow: No Pictures & Button Alteration

[kohnency]

1) Script Title: Flexi Slideshow

2) Script URL (on DD):http://www.dynamicdrive.com/dynamicindex14/flexislide.htm

3) Describe problem: I think I have all of my images in place, but they will not show up. Only the next/previous buttons. Also is there in easy way to change the color of the buttons or make your own buttons? The site I want to use it for is http://webtest.meredith.edu/acp11/default.htm

Are not pointing to valid images.

I tried a couple and got ths result:
The requested URL was not found on this server. The link on the ">referring page seems to be wrong or outdated. Please inform the author of ">that page about the error. If you entered the URL manually please check your spelling and try again.
Which leads me to presume they are not good links....
