I'm a new plugin coder, and I've spent several hours toiling away looking for reference and direction on this to no avail. Some direction or advice would be wicked.

My goal is to create an extension button that when clicked, executes a simple javascript line that displays http://imgur.com/* images below their links.

My problem is I've only been able to find reference to accomplishing this in a new frame, usually generated from pressing the button.The js line I'm using works in the url bar, and loads all the images underneath the links. How do I accomplish this same goal by simply pressing the button without creating a new window?

tldr: I wanna press a button that executes a javascript line in the active tab.

You know you could just use a bookmarklet for this?...but anywayz....
Basically you just need a background page to monitor for when the button is clicked and then inject some script into the page.
Heres an example......
