Thanks you, this code is good to add image in document body!
I am looking to add/insert image into header part, but not able to add properly. It will be helpful if you post program to add image into header of word document section using docx4j in java.

I have googled and tried some solution but still inporcess to achieve functionality (One of the URL -https://stackoverflow.com/questions/27318931/display-image-in-header-of-word-document-generated-by-docx4j/27323135)

Thank You in advance.

thanks very much

Thanks a lot, helped a lot.
