Add this to your custom CSS:

ul.products li.product img {
   border: none;
}

thank you! and if i want add product detail how can i add ?
style name -> (under) price ->(under) little sentence of detail
at the main page

I’m sorry but as you are using a commercial theme, you need to seek support from the theme’s vendors.

is there any case i can reduce of gap between pictures on main page ??

caz i want to match with main picture size

or how can i add banner adv next to main banner?

You’ll need to ask at WooThemes – they support their themes.
