Selecting one image from a table of images

Selecting one image from a table of images

Hi there,

I need some advice on how best to tackle building a voting page with Jquery. The basic (rude) layout is here...


Basically my actions are...

1. Voting disabled until user has entered a jquery verifiable email address, this also use ajax to check if there is an existing vote with the email address in the mysql table; if there is it does not allow further and shows a message.

2. When email address entered then user can click on one "best" and one "worst" image, when clicked on others in section change opacity with css. 

3. When clicked on a message appears "thanks for your vote" above the section and it makes an ajax call to a PHP file that registers the vote.

I am stuck on how to select one image and change the state of others in that section, then I'll move onto learning about Ajax.... any advice much appreciated, is for a not-for-profit but we could even pay something (gasp) :-)
