Use OnBeforeResHeaderRender and its innerHtml event attribute.
Comment posted by peter cli 18 years ago.
Does the image need to be a certain size ? Or should I override the img attributes ? This is what I have now :
e.InnerHTML = @" <img src='../Images/0.jpg' />";

The height shouldn't be more than EventHeight (default value is 17 (pixels); that is the minimum row height).
The width shouldn't be more than RowHeaderWidth (default value is 80 (pixels)).
You don't have to include height="" and width="" attributes but I would recommend adding them (it can improve rendering time because the browser will know the image size before actually loading it).
