Hi,

Sorry I am still feel puzzled about your explanation, Can I take it like this:

I can visit the page with ListView control by click links from different pages, different pages transfer different values to the ListView page, then I retrieve image info from database table according to these different values.

I write a simple demo to show what I expressing:

create table(different pages mapping different images):

CREATE TABLE [dbo].[Page2Image](
	[page_url] [nvarchar](50) NOT NULL,
	[image_url] [nvarchar](50) NOT NULL,
	[ext] [nvarchar](50)
)

.aspx page:

        <asp:ListView ID="ListView1" runat="server" DataSourceID="SqlDataSource1">
            <LayoutTemplate>
                <span id="itemPlaceholder" runat="server"></span>
            </LayoutTemplate>
            <ItemTemplate>
                Hello, You come from <%# Eval("page_url") %><br />
                <img src='<%# Eval("image_url") %>' alt="" />
                <hr />
            </ItemTemplate>
        </asp:ListView>
        <asp:SqlDataSource ID="SqlDataSource1" runat="server" 
            ConnectionString="Data Source=.\SQLEXPRESS;Initial Catalog=TestDB;Integrated Security=True" 
            ProviderName="System.Data.SqlClient" >
        </asp:SqlDataSource>

code-behind:

                string url = Request.QueryString["from"];
                SqlDataSource1.SelectCommand = "SELECT * FROM [Page2Image] where [page_url]=@url";
                SqlDataSource1.SelectParameters.Add("url", url);

links of different pages:

        <a href="WebForm3.aspx?from=WebForm1.aspx">WebForm3.aspx</a>

I am sorry I can't understand your meaning accurately, if you sent your code and explain it more clear, I can help you. You can refer to this temporary. 

If you still have any doubts, welcome ask me.
