Hi guys,

I have been lurking for a few days reading the awesome technical information threads, usages and opinions of many people. I have been blown away at how helpful you guys are, how much your community engages with each other and even the international markets you have! I'm sure I still have much more to learn.

Anyway, enough of my enthusiasm. I just wanted to quietly warn that attempts to hide serial numbers or other information in images while completely ignoring bar codes, and especially QR codes, may not be effective since it is trivial to read them even with a smartphone.

Thankfully, in this forum, some full sized images do not appear to be indexable by Internet search engines like Google.
