The specific steps are as follows:
1. Write our signature on a piece of white paper and send it to the computer.
2. Place the cursor in an appropriate position in the document, click the Insert menu, continue to find the Illustration tab under the Insert menu, and insert a picture.
3. Set the picture wrapping mode. Open its drop-down menu in the small triangle next to the "Wrap Text" option, and select the "Floating Above Text" option from the drop-down menu options.
4. Just adjust the position of the picture.
