How do WP folks handle a photo crawl or shuffle of photos on an intro page? In my current site I've done this by referencing a myspace photo crawl. http://ykfp.org/yakindex.htm
This visual element is commonly known as a "slider", and there are literally hundreds of plugins available to help you implement one. Search the WordPress plugin index for a list:
I like Flexslider: http://www.woothemes.com/flexslider/
I usually just create a custom-post-type called Slides, and then pull up 3 or 4 of the most recent slides (featured image)
It is very...flexible..you can even do videos with it.
I've sort of done it with Meta Slider. http://www.wordpress.ykfp.org/ But it looks like I'll next need to format all the photos to fit into my short and wide space better.
