Generating shadow from 2d image

[wingoku]

I wanted know if I can generate a shadow from a 2d image. For example: I have a coke cane and I want to generate a shadow such that it drops on the table or horizontal surface on right side of the coke. Then I want to create an image/bitmap of the coke & shadow combined. A little bit of hints will be very helpful.
