Hmm, it does look bad, especially since sylentwulf doesn't even offer an explanation.
This is yet another reason to bring up copyrights. We really need to stay away from slapping that label on everything we do. It is just going to end up with the lawyers making money and ruining our hobby.
Take the step-by-step cabinet building tutorial. Great work, I'm not knocking it, but...
The author claims copyrights to everything in the tutorial, and there is no mention of where he ripped the photos of the tools (copyright infringement). This can only lead to bad things.
I know you want to protect your hard work, but really think about it. In the end, is it worth it?
