XML THUMBNAIL Gallery HELP!

I NEED SOME HELP!!!

Ok, I took this gallery… http://www.kirupa.com/developer/mx2004/thumbnails.htm
and reverse coded it to how I want it to look and function. But, there are a couple of things I couldn’t figure out. If anyone can help with any of this, that would be awesome!

  1. when clicking on a ring circle, i need the alpha to change and to stay to show that the ring circle has been previously clicked on. (check out thinklab.com for reference)

right now i have it set where when you rollover the alpha is 50 to show currently what ring circle your mouse is on. now all i need is if you were to click on that same ring circle, for the alpha to be at 25 (and stay that way) to show it grayed out because it has already been clicked on. this in return shows users what ring circles are left to click on if they have missed any.

  1. when hitting back or next, it would be great if the alpha changed for the correct ring circle to show the user what image he/she is currently on. i’d say alpha 50 for this.

  2. every image that loads is stuck to the left, anyway to make it on the right instead?

  3. last one, if there’s a way to make it so that when the image loads, it fades in. i know this is controlled by alpha also.

if ANYBODY could help me with the coding that would be awesome. i’ve included a zip file with the neccessary files. if any of this is confusing, just PM me or reply here.
