I am not the right person for this add-on but definitely you are Bewertet mit 5 von 5 Sternen
For two days (48hrs) I tested this add-on on my tons of bookmarks and favorite websites. I feel so embarrassed, but all of my bookmarks and chosen links were not excitingly enough to contain any broken images.
But surely you visit many links with hidden images and will reveal them with this add-on. Highly recommended!
