Making Spacegallery Slideshow Auto-play?

I'm not a complete Javascript idiot but I am new to Jquery and not used to the way it's written so I'm having a little trouble figuring out how to do what I need to do. I'm working with the jquery slideshow called "spacegallery". Here's a link:[URL].. As you can see, when you click on the front image, it triggers the animation to the next slide. I'd like to set this up on a timer so it'll happen automatically.

Here's a link to the JS file doing the actual work:[URL].. The key function is "next", which starts at line 57. This function is "bound" to each individual image - I think, or maybe to the image container as a whole - at line 118.

I tried using setTimeout (line 191) to trigger "next", but it complains that "el is undefined". I think this is because "next" is expecting a parent node that was clicked - an image element or something like that.

So I think I need to figure out how to pass the current/front-most image element in my setTimeout call of "next". But I can't figure out how to get a handle on that element - doesn't seem to be an obvious array of image elements I can grab, or a current element counter.

Perhaps another approach would be to actually "click" the current main image element somehow in Javascript, so the code registers a click? Not sure if that can be done - can it?
