[HAF] How to add exception URLs to this Firefox extension

I use a Firefox extension for blocking all images. The extension only has an on and off function.

I would like to know how to add exception URLs to it so that some URLs are not affected.

So for example if I'm blocking all images, and I want Blackhatworld.com to not be affected, I want to know how to do that.

Also if I'm blocking all images and I want Blackhworld.com/specific-page/ to not be affected, I want to know how to do that.

Also if I'm blocking all images and I want Blackhatworld/category/* (wildcard) to not be affected, I want to know how to do that.

Extension: https://legacycollector.org/firefox-addons/5613/index.html

Version 3.1

I don't need an options page created or anything fancy. Showing me how to hard-code exception URLs directly in the code will do just fine.

I can pay $10 with Paypal for this job.

Thank you
