The 19thHole.com logo/watermark is placed on every image posted to the site. This is to prevent "outsiders" from using the images from our site. The logo is very small, and in most cases does not interfere with the image.
In the case where the image posted is very small also, then the watermark can overlay part of the image itself. The best way to prevent this is to make sure the image you upload is large enough for everyone to see clearly, usually 300x300 pixels at a minimum. The images can be as large as you like but normally 600x600 is about as large as most people want to see.
