WordPress the world’s most popular blogging platform comes up with drag and drop media just like Gmail.
It is really easy. Even what we had earlier was fun, I mean the flash uploader.
Here is what you need to do:
1. First Click the add media icon as seen below
2. Choose the drag and drop option (Switch to the new uploader), you will have to do this only once and WordPress will remember your choice
3. Now drag and drop any media, images or files into the box shown below:
The rest is almost the same. Happy Blogging
