HOW HOW HOW Does one access the zoho image library?

I have uploaed a boatload of images, yet everytime i wish to insert an image into mail - i get two options... from desktop and add URL.

Obviously THERE IS a way to access the library/ Perhaps it is a hidden icon, or maybe a pressure sensitive screen corner. or a dropdown list in the Marketing App?

Your response would be appreciated.
