How to include jsp file in a sub directory with relative images paths to root index file

Question

I have the index.html file with images stored at the same directory:

• home.jsp
• sub-dir
  • index.html
  • image.jpeg

and sub-dir content is a file uploaded by the user so in the index.html the image path is directly img src="image.jpeg" i need to include this index html to the home.jsp with the image preview.
