Watermark

Well, I never thought I would have to worry about my images being taken and used as someone elses.  Little ol' me?  Who would want to use my images as their own????  Well was I wrong...  I was doing a search to see if my infant sock corsages on etsy would come up during a search.  Well I found one pic of mine, but it was linked to SOMEONE ELSES page!!!!  And this person seems to be a very successful crafter, even does segments on tv!  I have asked her to give me credit for the use of my pic, we'll see if she does.  Lesson learned, I will be watermarking my images from now on.
