php - No such file or directory using move_uploaded_file()

I am working on my PHP code (insert_post.php) and I have two errors:

**Warning: move_uploaded_file(news_images/RaiderX.jpg): failed to open stream: No such file or directory in C:\xampp\htdocs\my_cms\admin\insert_post.php on line 106

Warning: move_uploaded_file(): Unable to move 'C:\xampp\tmp\php60F7.tmp' to 'news_images/RaiderX.jpg' in C:\xampp\htdocs\my_cms\admin\insert_post.php on line 106**

Everything is fine and I can see that data (images) is coming through to my mysql database but I cannot understand why there are these two errors.

This is the code:
