I have a homepage that has a section dedicated to a “slideshow”. It looks like this:

Each of the three bars at the right corresponds to an image. When the user stays on the page long enough without clicking anywhere, the images should start rotating automatically, but the user should also be able to click on one of the bars and display the corresponding image.
The closest plugin I was able to find that would handle the vertical bars is SlideDeck, but that’s a commercial plugin and this site is for a non-profit that doesn’t have a budget for these kind of things.
Sure, check out Easy Accordian.
