First up you can just drag and drop images from your computer into the text editor box.
Next you can also use the "Upload a File" Button thats below the editor, to select a image from anywhere on your computer or attached drives.
Got images in the Neotopia Media gallery? You can also add them to your posts via the Media Gallery button on the editor's toolbar. Clicking this button will show all your media from the Media gallery below the editor window and you can just click to add them into your posts.
Last up you can also add images from a URL via the image button on the toolbar (Old skool hey?)
Below you will be able to watch a fast video that shows the first 3 ways of adding images in action
