Add a Label On your Datalist...That Label Would be bind by the path.. like ~/Upload/image.jpg or ..Upload/image.jpg

<asp:datalist id="DataList1" runat="server" repeatcolumns="4" cellpadding="4" width="100%" ondeletecommand="DataList1_DeleteCommand" xmlns:asp="#unknown">

<asp:image id="Image1" imageurl="<%# String.Format("~/DistributorShopImages/{0}", Eval("ShopImagesExt")) %>" onclick="LoadDiv(this.src, this)" style="cursor:pointer" runat="server" height="200">
Width="200" />

<asp:label id="lbl_del_image" runat="server" text="<%#Eval("ShopImagesExt") %>" visible="false">

<asp:linkbutton id="Delete" height="22px" width="100px" runat="server" forecolor="Red" text="Delete" onclick="Delete_Click" />

C#

protected void Delete_Click(object sender, EventArgs e)

    {   

      DataListItem item = ((LinkButton)sender).NamingContainer as DataListItem;

       Label del_path = (Label)item.FindControl("bl_del_image");   //  Label Id

         string str =del_path.Text;
        String strPath = Server.MapPath(str);
     System.IO.File.Delete(strPath);

}
