I need help in creating a social bookmarking website.

Somefeatures that I'm looking for are as follows:

Visual Bookmarks
Photo Hotlinking/hyperlinking

Some similiar concepts are:

www.notcot.org (Based on Rails which I don't know how to code)
www.feedmyapp.com (Based on rails)
www.ilovenewwork.com (Based on Wordpress) Most Wanted
http://vi.sualize.us/ (Based with Scuttle and Thickbox)

Any templates for other CMS I'm fine with as well.
