CSS, Floating DIV javascript

Please review the following link. [login to view URL] I need one HTML page from the generated page above with css and javascript. I want much narrower rows (50% narrower in height) but the same mouse over effect to view the larger image. Shouldn't take much time for someone who knows what there doing. I'm assuming it could be a floating div next to each image to create the larger image. You can use jquery or javascript. Please make the css pretty. Toggle each row a different color (i.e. grey , white, grey white). Put a bottom border line underneath each row. Floating div will be the same height/width for each row.
