Answer 4

1.
<img src='petPhoto/<%# Eval("img")%>'></img>
2.
<img src='<%# "petPhoto/"+Eval("img")%>'></img>3.用sql拼接，给个别名 直接绑定如
sql：select 'petPhoto/'+ Imgurl as Imgurl  from table4.在后台写个方法，在绑定到控件上 
如  <asp:Image ID="ImgActivity" ImageUrl='<%# UrlCheck(Convert.ToString(DataBinder.Eval(Container.DataItem, "thumbnailURL")))%>' runat="server"/>

                                                                            <img src="petPhoto/<%#DataBinder.Eval(Container.DataItem, "数据库字段名")%>"/>
                                                                        </ItemTemplate>
                                                                    </asp:TemplateField>
