Doesn't show images when "load images" is turned of Rated 3 out of 5 stars
The addon let's you hide images on a page only after the images were loaded first. It won't show the images if you turned "load images" off. It thus isn't useful for showing images only for specific websites.
If you have "load Images" turned off in your browser preferences, then there won't be any images in the page to 'show'.
