// Get all shapes that contain images
NodeCollection shapes = doc.GetChildNodes(NodeType.Shape, true);

// Extract and save each image
int imageIndex = 1;
foreach (Shape shape in shapes)
{
    if (shape.HasImage)
    {
        string imagePath = $"Image_{imageIndex}.png";
        shape.ImageData.Save(imagePath);

    }
}

To save images in a specific format, simply adjust the file extension in the saving method.

4. Batch Extract Images from Multiple Word Documents

To extract images from multiple Word files, you can loop through a folder as shown below:

string[] files = Directory.GetFiles("input_docs", "*.docx");
foreach (string file in files)
{
    Document doc = new Document(file);
    NodeCollection shapes = doc.GetChildNodes(NodeType.Shape, true);

    int index = 1;
    foreach (Shape shape in shapes)
    {
        if (shape.HasImage)
        {
            string imagePath = $"Extracted_{Path.GetFileNameWithoutExtension(file)}_{index}.jpg";
            shape.ImageData.Save(imagePath);
            index++;
        }
    }
}

This method automates bulk image extraction from Word documents, saving you significant time and effort.
