In Badpuppy's early days, we used to have both on the model images. Over time the Puppy logo was removed, leaving just the site url along the left or right edge of the image, where it is not obstructing any part of the model itself.

It simply looked way too commercial with both the url and logo on the image. Even though the Puppies are so cute, it is more important to present the url on the image, laying the path for users to visit the site.

Since our pictures were constantly being downloaded and used all over, it was look at as a means of free advertising. Most do not take the time to crop off the url. When we did find, or get reported to us that our images were on a given site, we in most cases would contact them and end up turning it into a relationship where they'd promote Badpuppy in exchange for legal use of the images.

The url on the model images will suffice and we do the same thing with our model videos, but do so at the very bottom and small enough just to be seen, not where it interferes with the video.
