I want to display an ASP.NET image in the middle of a div (both horizontally and vertically), how should I arrange my div and image (image should be runat=server), also I should set max-width and max-height styles for my image, DIV acts as a placeholder, and my image should be inside the DIV, and it should be exactly centered both horizontally and vertically, can you show my the correct HTML and CSS? is there any sample?
