How do I display an image spgridview? I believe I need to create a custom field and bind it to the SPGridView.  I also need the image to generate a tool tip on a hover over.

I dont know if there is an easier way but I was able to create a custom field by creating an object that uses the ITemplate interface
using System;
using System.Collections.Generic;
using System.Text;

using System.Web.UI.WebControls;
using System.Web.UI;
using System.Web;
using System.Data;
using Microsoft.SharePoint;
using Microsoft.SharePoint.WebControls;


namespace BRTRC.App.WhitePages.Assembly.WebControls
{
    class TemplateImageDisplay :ITemplate
    {
        ListItemType _TemplateType;
        private string _ColumnName;
        /// <summary>
        /// 
        /// </summary>
        /// <param name="type"></param>
        /// <param name="colname"></param>
        public TemplateImageDisplay(ListItemType type, string colname)
          {
              _TemplateType = type;
              _ColumnName = colname;
          }
         /// <summary>
         /// 
         /// </summary>
         /// <param name="container"></param>
          public void InstantiateIn( Control container )
          {
              Literal lc = new Literal();

              switch (_TemplateType)
              {

                  case ListItemType.Header:
                      lc.Text = _ColumnName;
                      container.Controls.Add(lc);
                      break;
                  case ListItemType.Item:
                      Literal l = new Literal();
                      l.DataBinding += new EventHandler(button_DataBinding);
                      container.Controls.Add(l);
                      break;
                  default:
                      break;

              }
          }
         /// <summary>
         /// 
         /// </summary>
         /// <param name="sender"></param>
         /// <param name="e"></param>
          void button_DataBinding( object sender, EventArgs e )
          {
              Literal l = (Literal)sender;
              string localText = String.Empty;
              SPGridViewRow container = (SPGridViewRow)l.NamingContainer;
              bool imageFound = false;
              localText = ((DataRowView)container.DataItem)[_ColumnName].ToString();

              try
              {

                  if (localText.ToLower().Contains(".jpg,"))
                  {
                      localText = localText.Substring(0, localText.ToLower().IndexOf(".jpg,") + 4);
                      imageFound = true;
                  }
                  if (localText.ToLower().Contains(".png,") && !imageFound) 
                  {
                      localText = localText.Substring(0, localText.ToLower().IndexOf(".png,") + 4);
                      imageFound = true;
                  
                  }

                  if (!imageFound)
                  {
                      l.Text = Constants.UNKNOWNIMAGE;
                  }
                  else {

                      l.Text = "<img class=\"ImageSize\"src=\"" + localText + "\"/>";
                  }
                  
                  
              }
              catch { l.Text = Constants.UNKNOWNIMAGE; }//Unknown-Person.jpg
              
          
          
          }

    }
}

It worked and it lays out a blue print to create future custom fields
