Hi,

Thanks for your inquiry.
I open the Html(input.html) with browser(Microsoft Edge), but I didn’t find the image between second paragraph and third paragraph, as shown in the following screenshot.

In addition, I converted the html(input.html) to word file with Microsoft-OfficeWord, and I can’t find any image, as shown in the following screenshot.

Hi,

Thanks for your feedback.
I found that two images in your input html file, the type of one is base64, as shown in the following screenshot

And the typy of other one is a url, I try to access this url via browser, but there exist the limitation of user login, so I can’t access this image. I think this is the reason of lacking of image.

Hi,

Thanks for the more message you provided.
I noticed that you replaced the second image url, but the warning message is thrown when I attempt to access this url, as shown in the following screenshot. Therefore, when convert this html to word file, the image also can’t be obtained. I believe that you can access this url through browser due to you have been authorized, but there are not authorized while running the program.

In addition, I had a test, I replace the second url to other image url which can be accessed, the image exists in the result word file and pdf file. I attached the files for your reference.
