Rendering menu > Render > Render Scene dialog > Renderer panel > Watermark Parameters rollout
Controls on the Watermark Parameters rollout let you add a watermark to the rendering.
Note: This rollout is available only with the default scanline renderer.

Render—When on, renders the watermark image in your rendered image or animation. A watermark image must be loaded before it can be rendered. Default=on.
Load—Enables you to select an image to use as a watermark.
Blend value—Blends the watermark image with the rendered image. Determines the opacity of the watermark placed in the rendered image or animation. Default=0.251. Range=0.0 to 1.0.
Image Top—Specifies the vertical placement of the watermark image: the uppermost pixel in the rendered image or animation at which the watermark image will be rendered.
Image Left—Specifies the horizontal placement of the watermark image: the leftmost pixel in the rendered image or animation at which the watermark image will be rendered.
