Facebook Login Application using the JavaScript SDK

I want a Facebook application running on facebook canvas. I'll be sharing some valuable codes on it. In order to gain access to theses codes pages, user should login/connect to the app from the canvas itself on Auto without clicking on a login button ([login to view URL]), after successful login I want the user's Facebook profile picture to be visible on the canvas page (just to personalize the experience). each user can visit the codes page 5 times/24 hours, so a simple text showing (vistit 1, visit 2 ... visit 5) is required, HTTP cookie could be used for that purpose. I have 3 categories of codes to be shared, the login should be possible from ([login to view URL], [login to view URL], and [login to view URL] ) and after successful login, visits coming from [login to view URL] should be redirected to the page having the 1st category codes page, and the same goes for the 2 other categories. When the login dialog shows up I want some graphics loaded in the Canvas iframe background under the login dialog By using the JavaScript SDK to build a client-side login experience, as shown in this picture: [login to view URL] and explained in this page : [login to view URL] So, in the end all what I'm expecting is the login and redirection to be as described and the canvas page showing the user's profile picture ONLY and the visits number. I can handle the rest.
