This is v3. I hope it doesn't die off like it did the last 2, because this was fun.
HOW TO CUROIOOAP{BOABFBFBFFFF AN IMG
Okay, you're going to need Notepad++. Notepad++ is a complex scripting program that allows you to make scripts. This has so many ways to take advantage of breaking images. In the 2nd version of corrupt an image, I posted that there was a update with notepad++. You can't delete too much of the image or it will actually BREAK the format. This can't harm your computer, but it will cause the image to stop being an image. I'll kick it off.
Be aware that these corruptions are able to turn pink and girly at any moment. While corrupting an image, keep Notepad++ open just incase you accidentally corrupted it too much, because you can undo certain deletions.
