How to display images from project folder to DataList in ASP.Net

I am first working on this module. Target is to show all the pictures from images folder to datalist. I myself got the code from other sources and not getting the logic that's why I am continuously receiving error..

 <asp:DataList ID="dlpic" runat="server" RepeatDirection="Horizontal" RepeatColumns = "4">
       <ItemTemplate>
               <img src='<%# Bind("Name","~/images/Gallery/{0}") %>'   class="scale-with-grid" />
                <a id="imageLink" href='<%# Bind("Name","~/images/Gallery/{0}") %>' class="zoom prettyPhoto" runat="server" >
                  </a> 
          </ItemTemplate>
 </asp:DataList>

and here is server side code

  string[] filePaths = Directory.GetFiles(MapPath("~/images/Gallery/"));
            List<ListItem> files = new List<ListItem>();
            foreach (string filePath in filePaths)
            {
                string fileName = Path.GetFileName(filePath);
                files.Add(new ListItem(fileName, "images/Gallery/" + fileName));
            }
            dlpic.DataSource = files;
            dlpic.DataBind();
