How do you link an image from a DBImage component in Delphi 2007 to a Bitmap component in Rave Reports?

So, I have a database with a bit of information and an image for each entry.  I am trying to then print a Rave Report using that data.  All of the text fields are quite easy, but what I am having trouble with is displaying the image.  The bitmap component can be given an input property, but when I pass the picture on to the property that I declared previously, I get an incompatible data type error, as the property expects a string, not a TImage.

Basically, what I want is a line of code that looks like this

RvProject1.SetParam('Image', DBImage1.Picture);

but will actually work if I pass it a picture.  Or, some way of creating a parameter in Rave Reports that can be passed a picture.
