Penetration testing blog

This is meant for replacing your own watermarks, not for the purpose of stealing someone else’s content!

But using imagemagick (http://www.imagemagick.org) you can easily replace a portion of the image (*.jpg in this case) with the portion that goes on top, your new logo for instance (litte.gif in this case):

@echo off
for %%X in (*.jpg) do composite -geometry +0+178 little.gif “%%X” output/”%%X”

The -geometry option is for providing a specific horizontal and vertical position within the original image.

What does it have to do with penetration testing you may ask - well it could come useful during a client-side attack where you need to reuse several images quickly, or simply related in the fact that during a period of time where you run out of work, you can work as a designer? oh well.

Hope it helps, it sure helps me remember.
