I need to censor some images (Whole image).
I need these images for a essay about pornography in a webpage and I need the images (pornographic pictures) be censored (something like a pixelized image so the viewer should be able to understand it's about pornography but shouldn't be able to see the original image).
I'm using GIMP.
I used "Filters->Blur->Pixelize".
But my problem is, when the viewer zooms out on image, he can see the original image! (When the image gets very small -- less than 200px or 100px -- the original image is detectable just like a low resolution picture that is clearer when it's zoomed out and is smaller).
How can I overcome this? (for example by randomizing pixels when pixelized)
