    Show tif or pdf in DataList

    I have a DataList control that shows jpg and gif images just fine. I am
    filling the DataList from a list of files in a directory. The directory
    might contain tif and pdf files but all that shows in the DataList is the
    red X for these files. Am I asking it to do something that is not possible?
    If not, are there any alternatives to showing a reduced image for other file
    types in a DataList? Thanks.
    My DataList control is shown below.

    <asp:DataList ID="PicturesInF older" runat="server"
    CellPadding="3" Visible="true" BorderColor="Bl ack"
    ItemStyle-BorderWidth="1p t"
    ItemStyle-BorderColor="Bl ack" ItemStyle-BorderStyle="So lid" Width="540"
    RepeatDirection ="Horizontal "
    RepeatLayout="T able" RepeatColumns=" 3"
    OnItemDataBound ="PicturesInFol der_ItemDataBou nd">
    <ItemTemplate >
    <asp:Image runat="server" ID="Picture"
    ImageUrl='<%# Eval("FullName" ).ToString() %>' Width="180" Height="135" />
    </ItemTemplate>
    <AlternatingIte mStyle BackColor="Tran sparent" />
    </asp:DataList></td>

      To shed some light on your issue, you should view the resulting webpage
      source with the image tag and it's image path.

      If the path is NOT to an ~/images/ folder w/in your webapp, you should try
      placing a few sample images as such - storing images in other locations where
      permissions, mappings are not universal could be your problem.

      If this is still an issue, you may wish to post a followup with any new
      considerations or responces to the points I've raised.

          Jeff,
          The DataList does generate img html tags as output and the src is a path to
          the file.
          The images are in a virtual directory on the website e.g. /photos so
          permissions is not an issue.

          p.s. Do you know how I could create a stream for these images and populate
          the DataList? I have not worked with Streams before. Thanks.

          David
