Set pagination in portfolio listing

Hello

When We open portfolio page. there is default listing of other portfolios above the footer. We are unable to show pagination as it works for blog widget etc. It shows only 4 portfolios.

And 1 more thing, this portfolio listing under portfolio detail page also shows the same portfolio in the listing whose detail is opened. It should not show the same portfolio at bottom listing in portfolio detail page.

I know you can do it. Please help us.

Thanks
