  the latest release of fastreport, new features have been added :
  
  Version 2017.1

  ---

  [Core]
  + added possibility to set picture location (URL) in PictureObject from database (I have not try this version)
  + .....
  
  
  if you use old the version of fastreport, you may use script in frx file.
  

  public class ReportScript
    {
  
      private void Data1_BeforePrint(object sender, EventArgs e)
      {
        Picture1.ImageLocation = (String)Report.GetColumnValue("MainReport.ImageColumn");
      }
    }
  

  
  in your asp.net code, the imagecolumn is referring to full path location of your images in the server, for example :
  HttpContext.Current.Server.MapPath("~/upload_image/") + "1001.jpeg"
  HttpContext.Current.Server.MapPath("~/upload_image/") + "1002.jpeg"
  ....

  I'm afraid you can't, you need a location (full path) in the server in order to set picture location, not virtual directory (../image/). To get full path, use function Server.MapPath in webform, or HttpContext.Current.Server.MapPath in MVC.
  
  if you want to do that in script, you must set a reference to use server.mappath function, never tried before.
  
  I will use this scenario :
  1. i have a datatable with fields :
  * ID int = 1
  * Name string = MyName
  * Picture string = 001.jpeg
  
  2. modify field Picture with full path location
  foreach (row in rows)
  {
  string img = row.Picture.ToString();
  row.Picture = HttpContext.Current.Server.MapPath("~/upload_image/") + img;
  }
  
  3. push datatable to fastreport
  4. use script to attach column picture to PictureObject
  
  please inform in this forum if you have succeded with using server.mappath in the script. and about the performance speed.

  I have tried your method, success :
  
  1. add referenced assemblies in fastreport designer, menu report => options => script => add =>
  in my case, x86 system, C:\Program Files\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5\System.Web.dll
  
  2. script

  using System;
  using System.Collections;
  using System.Collections.Generic;
  using System.ComponentModel;
  using System.Windows.Forms;
  using System.Drawing;
  using System.Data;
  using FastReport;
  using FastReport.Data;
  using FastReport.Dialog;
  using FastReport.Barcode;
  using FastReport.Table;
  using FastReport.Utils;
  using System.Web;
  
  namespace FastReport
  {
    public class ReportScript
    {
      string basePath = HttpContext.Current.Server.MapPath("~/Content/");
      private void PageHeader1_BeforePrint(object sender, EventArgs e)
      {                                                                                     
         Picture1.ImageLocation = basePath + "login.png";
      }
    }
  }
  

  
  3. maybe, easier method, just passing HttpContext.Current.Server.MapPath("~/Content/") as report parameter, no need to set reference in the script, just Picture1.ImageLocation = (String)Report.GetParameterValue("ImageFullPath");
