Either click here to edit or replace this text with your own, or delete the block from the options on the left, or drag sample content layouts from the right, then replace those images/videos with your own.

If you don't like this editor mode, you can select other editor modes from the top right where it says Drag & Drop. TinyMCE3.5.10 is the old editor mode, good for tablular based formatting.

 
Drag and drop images into the page.
