Steps to save images into a folder and use that path in Word to HTML conversion

Create a new C# .NET Core console application project.
Install the Syncfusion.DocIO.Net.Core NuGet package as a reference to your .NET Core applications from NuGet.org.
Include the following namespace in the Program.cs file.

using Syncfusion.DocIO;
using Syncfusion.DocIO.DLS;

Use the following code example to save images into a folder and use that path in Word to HTML conversion.

//Load an existing Word document. 
using (FileStream fileStreamPath = new FileStream(Path.GetFullPath(@"../../../Input.docx"), FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
{
    //Load the file stream into a Word document.
    using (WordDocument document = new WordDocument(fileStreamPath, FormatType.Docx))
    {
        //Create a file stream.
        using (FileStream outputFileStream = new FileStream(Path.GetFullPath(@"../../../WordToHtml.html"), FileMode.Create, FileAccess.ReadWrite))
        {
            //Hook the event to customize the image. 
            document.SaveOptions.ImageNodeVisited += SaveImage;
            //Save the html file to the file stream.
            document.Save(outputFileStream, FormatType.Html);
        }
    }
}

Use the following helper method to save images into a folder and use that path in Word to HTML conversion by using ImageNodeVisited event.

static int imageCount = 0;
static void SaveImage(object sender, ImageNodeVisitedEventArgs args)
{
    //Customize the image path and save the image in an external folder.
    string imagepath = @"D:\Temp\Image_" + imageCount + ".png";
    //Save the image stream as a file.
    using (FileStream fileStreamOutput = File.Create(imagepath))
    args.ImageStream.CopyTo(fileStreamOutput);
    //Set the image URI to be used in the output HTML.
    args.Uri = imagepath;
    imageCount++;
}
