How to make a watermark on the image

[snowforest]

Thanks I did it. I don't think a plugin is necessary. What you described seem sufficient, I am not sure what else I might want about it.

And for my learning, what do you mean by #7?

And I see a separate layer for the text, is it necessary to merge it with the picture layer? (without doing so, I could still get the jpg image with watermark which was my ultimate goal here.)
