Question

I have some thumbnails that I display with a Repeater, using a hyperlink and image control. I want to be able to click on a thumbnail, display the bigger image on the same page and I want the imagename to be part of the URL. Im really stuck right now. Do I use QueryString or..?
My hyperlink now looks like this:

<asp:HyperLink ID="HyperLink" runat="server"      NavigateUrl='<%#Eval("name","Content/Images/{0}") %>' ImageUrl='<%#"Content/Thumbnails/" + Eval("Name") %>' >HyperLink</asp:HyperLink>

Edit
Yes, the path to the images is: ~/Content/Images/.
Here’s some of my code behind, maybe it helps to explain what I’m doing.

protected void Page_Load(object sender, EventArgs e)
{
    string imgPath = Server.MapPath("~/Content/Images/");
    List<FileInfo> images = new List<FileInfo>();

    DirectoryInfo directoryInfo = new DirectoryInfo(imgPath);
    FileInfo[] fileInfo = directoryInfo.GetFiles();

    foreach (FileInfo file in fileInfo)
    {
        images.Add(file);
    }

    FileRepeater.DataSource = images;
    FileRepeater.DataBind();

}

protected void UploadButton_Click(object sender, EventArgs e)
{

    var file = ChooseFileUpload.FileContent;
    string fileName = ChooseFileUpload.FileName;

    var si = Gallery.SaveImage(file, fileName);
 }

Yes…QueryString should be fine…it can be something like

Content/Thumbnails/page.aspx?imageName=”your image name”

Update:

Where are the images stored…do they have a unique value/identity?…if yes then instead use a url of something like

Content/Thumbnails/page.aspx?imageid=”your image id”

this should be the navigate url of your thumbnail image hyperlinks… and when the user clicks on a thumbnail…just make a query/call to wherever the images are stored with the id value in the querystring….you can ready querystring value by Request.QueryString[“imageId”] in your case…
