For images which have been split apart across multiple files, LEADTOOLS can be used to consolidate them into one composite image. Here's how to use the CombineCommand to recreate an image previously divided.
https://www.leadtools.com/help/leadtools/v19/dh/pe/combinecommand.html

Code:


 using (RasterCodecs codecs = new RasterCodecs())
 {
    RasterImage left = codecs.Load("cropthird.jpg");
    RasterImage center = codecs.Load("cropthird2.jpg");
    RasterImage right = codecs.Load("cropthird3.jpg");

    RasterImage newImage = new RasterImage(RasterMemoryFlags.Conventional, left.Width + center.Width + right.Width, left.Height, 24, RasterByteOrder.Rgb, RasterViewPerspective.BottomLeft, null, null, 0);

    CombineCommand cc = new CombineCommand();

    cc.SourceImage = left;
    cc.DestinationRectangle = new LeadRect(0, 0, left.Width, left.Height);
    cc.Run(newImage);

    cc.SourceImage = center;
    cc.DestinationRectangle = new LeadRect(left.Width, 0, center.Width, center.Height);
    cc.Run(newImage);

    cc.SourceImage = right;
    cc.DestinationRectangle = new LeadRect(left.Width + center.Width, 0, right.Width, right.Height);
    cc.Run(newImage);

    codecs.Save(newImage, "combinedimage.jpg", RasterImageFormat.Jpeg, 0);
 }
