The example below shows how to load a 1000 by 1000 twips image from a stream and insert this image at the beginning of the main sub-document:

@using System.IO
@* ... *@
<DxRichEdit @ref="richEdit" />

@code {
    DxRichEdit richEdit;
    Document documentAPI;
    @* ... *@
    /* Surround the code that contains an asynchronous operation with a try-catch block to handle
    the OperationCanceledException. This exception is thrown when an asynchronous operation is canceled. */
        try {
            documentAPI = richEdit.DocumentAPI;
            @* ... *@
            FileStream sourceStream = File.Open("file-path-to-your-image", FileMode.Open);
            DocumentImageSource imgSource = DocumentImageSource.LoadFromStream(sourceStream, 1000, 1000);
            InlineImage newInlineImage = await documentAPI.InlineImages.CreateAsync(0, imgSource);
            @* ... *@
        }
        catch (OperationCanceledException e) {
            Console.WriteLine($"{nameof(OperationCanceledException)} thrown with message: {e.Message}");
        }
}
