HTML to HTML - how are images handled?

### Question

I am trying to convert HTML files to HTML. What I notice is that img tags are missing in the output. During conversion, I see "could not get image" errors. Is this the expected behaviour? Input HTML is derived from docx using mammoth. I am using mammoth because I am trying to retain anchor links that were present in docx. I am hoping docling will preserve anchor links and anchors when I give it a plain HTML file as input.
