You can simply put a 'PictureBox' control to your form and set its 'ImageLocation' property with the URL you are getting from database itself. This will take care to display the image from the specified path.
Ex :-
pictureBox1.ImageLocation = @"D:\SMRUTI\Projects\CodeProjTest\TestApp2-Win\Images\chat1.jpg";
Hope this will definitely of help to resolve your issue.
