Want to add graphics to the silkscreen layer

How does one go about adding graphic elements (company logo etc…) to the silkscreen layer on a board. Is this done after generating the gerber or is there a way to import bitmaps into Eagle?

Thanks,

Jamie

Yet again, I answer my own post. There are some ULP scripts on the Cadsoft site for loading bitmaps into Eagle. They convert monochrome pixels into rectangles. This way you can have a nice logo in your silkscreen layer.
