I'm looking to essentially build the same thing as  teemagnet.com   (this link goes outside odesk.com) .  On teemagnet.com they are pulling down 8 images each day from other websites and showing them.  I'd like to do the same.  
Ideally I'd like to pull down these image automatically every day, then post / display them on my new website.  
I'd love to utilize Wordpress and make a new "post" every day which would contain the new images, so everything is archived.
