Yes. On the Photo Detail page (see here for example), underneath the photo you'll see a link that says "Layout Version."
A layout version is a watermarked version of the original photo that you can use for internal drafts and mock-ups.
Our layout versions include the photo ID, the photo credit as well as a short URL which means once you're ready to buy the full size photo, you'll be able to find it again a snap.
NEW: People who have previously purchased photos from us have now access to watermark free layout versions. If you haven’t bought photos from us yet, you can fill out and submit an agreement form to get access to watermark-free layout versions.
