How to fade right & bottom photo edges

 I am working on a flyer in CorelDraw and I am stuck on something.  I need to include a photo and I need the right side and bottom side of the photo to fade away.  The edge where the photo begins to fade should not be straight nor should it be a smooth circle/ellipse.  I tried doing this with the transparency tool in CorelDraw but I can't control it enough to end up with the effect that I need.  I figure I probably need to select "edit bitmap" and pop into Photo-Paint but I am far less knowledgeable in Photo-Paint than I am in CorelDraw.  Can someone give me some advice or point me to an online tutorial for this?

Thanks.
