Problem to limit slider to Homepage

Hello, I m a new user of Wordpress with the template simple catch Pro I have some troubles with the slider. 1. I would like to limit its display to homepage. When i try to limit the display of slide to "homepage/frontpage", i can't see it, in all pages. When i check "entire site", i can see it, but naturally in all pages of the website.... 2. I wood like to use a square picture for the post in listing pages, but if i do that, the slide is to small and in a bad size.. Can you tell me what i'm doing bad ? You can see the testing website : http://daniel.odiso.com Thank you by advance. DV
