I need your  help addressing 2 challenges that I'm currently facing right now with my sites project.

1. I would like my homepages' slideshow images to display in full i.e 990x350. I have tried working around with the tables using 1 column @ 350 and one row @ 990, but still no luck. 
   
   
2. After creating/inserting a contact form with CAPTCHA on my contact page, I have noticed that there is no refresh button to refresh the code, is there any way I can edit the code and force it to display this?
