Another way to solve my probelm would be to add my own custom button with a post back. Trouble is I can either have a button with no image (postback works) or an ImageButton with no post back? Please help I have been trying to solve this for hours.

            Button btSave = new Button();                        // Works but cant have image
     or    ImageButton btSave = new ImageButton();     // Has image (no hover) but postback does not work (does not save data)
            btSave.ID = "btSave";
            btSave.CommandName = "Save";
            btSave.ImageAlign = ImageAlign.AbsMiddle;
            btSave.CausesValidation = false;
            btSave.ToolTip = "Save";
            btSave.CssClass = "ButtonAsImage";
            btSave.OnClientClick = "return SavingWP()";
            btSave.ImageUrl = "/CS/RTFEditor/Images/Save.gif";
            this._tb.InsertToolControl(1, "MySave", btSave);
