Hello my friends! Ok first of all what you need to do is go directly to your plugins section in WordPress and type OneNote Publisher, install the plugin and follow the instructions that are very straight forward.
Next you need to do is go to OneNote and create a new note book and call it Blog_Posts (call it as you wish but make sure you use that note book only for your posts for wordpress).
Next step is to go to wordpress and create a new post, there you will find a new button with the image of OneNote, click on it and viola !! Your post will appear simple as that even if you are posting with images. Hope you find this helpful .
Keep it real my friends
