Images

When you select the "Insert Image" button from within the WYSIWYG, a small drop-down window will appear with the available images you can insert.

Images can be inserted based on what's available from the "Media" portion of that piece of content. More on how to upload images to the Media section can be found here.

Once an image is inserted, you have the option to align it left, right, or centered.

Aligning the image left or right will shrink the image down to 50% width and wrap the text to either the left or right of that image. Center will stretch it to 100% width. This is the only form of embedded image resizing available.
