    Hello AbbottF,

    Thank you for your question.

    I am not sure how you create the PDF document, I will assume that you use dynamic approach.

    My suggestion is to use CellExporting server event, and from there to modify the cell element content.

    To be more specific AddContent Method can accept image and hyperlink data, I think this is what you are searching.

    Sample is attached.

    Code snippet:

    protected void dExporter_CellExporting(object sender, Infragistics.Web.UI.GridControls.DocumentCellExportingEventArgs e)
    {
     if (e.GridCell != null && e.GridCell.Column.Key == "Test")
     {
      if (e.GridCell.Row.Index == 2)
      {
       Infragistics.Documents.Reports.Report.Text.Style bluelink = new Infragistics.Documents.Reports.Report.Text.Style(new Font("Aria", 8, FontStyle.Underline), Brushes.Blue);

       string reff = e.GridCell.Value.ToString();
       var regexHref = new Regex("<a [^>]*href=(?:'(?<href>.*?)')|(?:\"(?<href>.*?)\")", RegexOptions.IgnoreCase);
       var regexSrc = new Regex("<img [^>]*src=(?:'(?<src>.*?)')|(?:\"(?<src>.*?)\")", RegexOptions.IgnoreCase);
       var urls = regexHref.Matches(reff).OfType<Match>().Select(m => m.Groups["href"].Value).SingleOrDefault();
       var srcs = regexSrc.Matches(reff).OfType<Match>().Select(m => m.Groups["src"].Value).SingleOrDefault();
       
       Infragistics.Documents.Reports.Graphics.Image img = new Infragistics.Documents.Reports.Graphics.Image(HttpRuntime.AppDomainAppPath + srcs);
       e.ReportCellElement.AddText().AddContent(img, new Size(70, 70), Infragistics.Documents.Reports.Report.ImageAlignment.Middle, new Hyperlink(urls));
      }
