Image in crystal report

Hi all,

I have crated crystal report and attached through store procedure but some reason i need to show signature from different table.

i dont want to join table in store procedure.

i need solution like: crystal report field = path of image

i done it for text field : rptDoc.DataDefinition.FormulaFields["crystal report field"].Text = "'" + my control.Text + "'";

is this possible to do for image.

Regards
