Spiders To Kittens (Image Replacer) โดย Christian Deneke

Are you scared of spiders? Or just not fond of looking at them? In that case you're in for a treat. If you like kittens more than spiders, that is. ;)

This Add-On will automatically replace any image that contains a spider-related word in its url, title or alternative text with that of a cute kitten.
On top of that, it will also check for background images and if an image is contained inside a link, it will also check the link. Just in case. You never know, where they hide.

By the way, in case you're wondering about privacy:
The all images are delivered along with the Add-On and spider-detection is based on keywords that are also part of the package. So there is no communication with any other server whatsoever, it all happens only on your machine.
