Yes...thanks WIM.
I was looking through my portfolio and noticed the Shutterstock
watermark was covering up an important feature on the image
when you're viewing it simply as a thumbnail. If indeed Shutterstock
doesn't allow you to go back and shift the watermark logo (in my
case I'd place it at the bottom) then it might be a "heads-up"
item when you're preparing your image for submission, especially if you're
like me, and never payed attention to that feature. Lesson learned
but I DO wonder why Shutterstock doesn't include that with re-editing your images.
