image end of textbox with dynamic height

[shedayat]

I have a letter with header and footer in which the text of the letter is written in the body, so that the value of the allow html property is true.
At the end of this letter, an image will be placed as a signature of the letter.
Sometimes the preview of the letter is displayed correctly, but in the pdf output, the signature does not appear at the end or is displayed.

Please provide guidance on what is the most appropriate way to do this?
