For instance

You need to have a way to specify where your images will be stored in your app. Therefore you need a web config file with the path in it. Or if you want to be really creative, you can store it in a database....

In your Web Page

    <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Images.aspx.cs" Inherits="ImageViewer" %>


    
    
    
        
        
    
    
        

            

                
Viewer Demo
                
            
                

                    
Using Viewer with the Repeater Control
                    
Repeater control to display a collection of images.
                
                

                
                    
                        
                    
                
                
                
                
    
            
        
    
    

In your web.config

and In your code behind .cs file You really need to filter files, that way if someone( maybe you ;) ) puts erroneous files in it, you won't inadvertently include them...

    string filters = "*.jpg;*.png;*.gif";
    string Path = ConfigurationManager.AppSettings["FilePath"].ToString();

    List images = new List();

    foreach (string filter in filters.Split(';'))
    {
        FileInfo[] fit = new DirectoryInfo(this.Server.MapPath(Path)).GetFiles(filter);
        foreach (FileInfo fi in fit)
        {
            images.Add(String.Format(Path + "/{0}", fi));                 
        }
    }

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