We are just like you, some humans who very treasure original work from every one, no exception! That's why we always keep the original photos without single change including the watermark. Each photos gallery we include are always carrying website or blog link where it belongs to be below each photos. Common thing is people ask about the proper right about the images on our gallery. When you need to ensure what is your right, you have to contact the website on each images, the reason is we cannot determine your right. Do not forget, if you don't see watermark does not mean the images can be freely used without permission.
