GroupDocs.Markdown provides several strategies for handling images during conversion. Set the ImageExportStrategy property on ConvertOptions to control the behavior:
Base64 embedding – inline images as data URIs using ExportImagesAsBase64Strategy.
File system export – save images to a directory using ExportImagesToFileSystemStrategy. Use the ImagesRelativePath property to control the relative path written into Markdown image links.
Skip images – omit all images from the output using SkipImagesStrategy.
Custom handler – implement IImageSavingHandler for full control over image saving, including renaming and custom storage via CustomImagesStrategy.
