Actually this is for a new channel I plan on launching sometime (hopefully really soon) that has nothing to do with cows. I have been on YouTube for a long time uploading crappy videos (and if you've seen them you'll know) and I want to have a new well branded channel with quality content. The logo in the thumbnail is just something I want to do to make my branding stronger and I want to know the right place to put it and hear what other people think. But I think I will go with number 3 for the watermark, thanks for the help.
