Is there an easy way to add images to a post without having to add a URL to an image...like inserting an image into a post? Or multiple images?

With a plugin like ABP Imgur

You should see the "attachments" window at the bottom of your posting page.  It's a simple "drag & drop" window for images.
Like this image which was from the desktop.

Or this image which was dragged from another website onto the attachments page.
