Creative users of image board began the comical assault digitally manipulating ISIS propaganda photographs to tease the abhorrent terror group.

One 4Chan user came up with the sardonic idea, writing: “How about castrating the image of ISIS by replacing the faces on ALL the propaganda photos with bath ducks?”

Since the post, scores of Photoshop masters have pasted the heads of rubber ducks onto pictures of savage ISIS fighters.

The images have been shared in an album titled ‘creates the duck state’ - which has been viewed more than 100,000 on photo-sharing site Imgur.

One user sarcastically wrote: “Great, now I’m scared to take a bath.”
