can you please post your aspx page code?

You have wt="width=" and you gave wt+"=50" which implies width=="50". I think something is wrong here ;)

Try below solution

in aspx code

<asp:DataList ID="dtlist" runat="server">
        <ItemTemplate>
            <asp:Image ID="imgsource" ImageUrl='<%# Eval("ImageUrl") %>' runat="server" />
        </ItemTemplate>
    </asp:DataList>

in code behind page

DataTable dt = new DataTable()
           DataColumn dc = new DataColumn("ImageUrl");
           dt.Columns.Add(dc);

            ArrayList pics = new ArrayList();
       string html;
       DirectoryInfo dirs = new DirectoryInfo(Server.MapPath("~/images"));
       html=dirs.GetFiles("*.jpg").Count().ToString ();
       foreach (FileInfo s in dirs.GetFiles("*.jpg"))
       {

           DataRow dr = dt.NewRow();
           dr[0] = s.Name;
           // you change your code as per need .
           dt.Rows.Add(dr);
       }
                   dtlist.DataSource =dt;
                  dtlist .DataBind ();

               }

hope this will help:)
