Question/help about asp:literal

[Kenichi666]

I am new to asp.net so please bear with me
Is it possibel to set or bind a <ASP:Literal> in one page and call it from another place???
fx.

Image/Image.aspx.cs

sb.AppendFormat("<img src='Image.aspx?Img=" + i + "'border='1' height='75' width='75'/><br /><br /><br />");
img.Text = sb.ToString();


default.aspx

<asp:literal ID="img" runat="server" />

How can i set this asp:literal to get data from Image/Image.aspx.cs???
