Answer 1

Assuming there are same number of images in both the folders, try this

String path = HttpContext.Current.Request.PhysicalApplicationPath + "images\\";
String crop_path = HttpContext.Current.Request.PhysicalApplicationPath + "images\\crop\\";

Create a new class

Class filenames
{
    public string filename { get; set; }
    public string crop_filename { get; set; }
}

and then in page load

protected void Page_Load(object sender, EventArgs e)
{
    string[] filesPath = Directory.GetFiles(Server.MapPath("~/images/"));
    string[] crop_filesPath = Directory.GetFiles(Server.MapPath("~/images/crop/"));
    List<filenames> files = new List<filenames>();
    filenames objfilenames;
    for(int i=0; i<filesPath.length; i++)
    {
        objfilenames = new filenames();
        objfilenames.filename = "~/images/" +  Path.GetFileName(filesPath[i]);
        objfilenames.crop_filename = "~/images/crop/" + Path.GetFileName(crop_filesPath[i]);
        files.Add(objfilenames);
    }
    gvDetails.DataSource = files;
    gvDetails.DataBind();
}
