Posts lose header image upon editing

Oh congrats,I glad to say that I have resolved the issue.After using small trick.

(I was getting a problem of page update time,header was automatically deleted.)

Go to ftp and follow this path in wordpress folder

/wp-content/plugins/hmk-add-images-for-categories-and-pages/hmk-adds-images.php

Open hmk-adds-images.php file

and paste below whole code.No need to change single line.
