You may be familiar with the brilliant extension known as Ncage, which replaces all images on webpages with pictures of the esteemed American actor Nicholas Cage. While this is humorous for a short time, victims quickly realize that they've been pranked and promptly disable the extension, ending the fun prematurely.

Enter nCage+! This extension allows you to implement a more subtle strategy by specifying the percentage of images that you would like to be replaced, rather than bluntly replacing all images. Add this extension to a friend or co-worker's browser and laugh as Nicholas Cage randomly shows up as they browse the web. It could be days or even weeks before they realize that something is up!

This evolution of the original concept includes a number of beneficial upgrades:

• customizable image replacement probability
• Image references that won't break over time
• Additional themed libraries. Choose from "Nicholas Cage", "Rubber Ducks", "Anime Girls", or "Censored" content.
• Improved image resizing and scaling

I plan to refine the image replacement behavior as well as include additional pranking features:

• increase the image replacement probability over time
• random link redirection (replace links on the page with custom locations)
• customized image libraries
• word/text replacement
