@Maybe-U You asked me to review. The code looks okay to me, but I'm really not all that familiar with TemplateProcessor, so it needs someone more knowledgeable to review. However, your test may have a problem. Does it actually attempt to read your external images? If the answer is no, there's no problem. If the answer is yes, I'll add some more comments.

However, in reality, it is possible to read external or local images, so my answer is yes. this is html content

this is output docx file

@Progi1984 can you review my code thanks you

My testing indicates that your test does attempt to load image https://t7.baidu.com/it/u=4198287529,2774471735&fm=193&f=GIF and will fail if it is not available; that is probably true of your second image as well. The problem is that external files tend to move or be deleted over time, and, when (not if) that happens, the unit test suite will fail. To avoid this problem, I think you might be able to use AbstractWebServerEmbeddedTest so that the requests are routed to localhost rather than an external site. Again, I'm not all that familiar with it, but there are a lot of tests that use it (e.g. HtmlTest).
