Inserting images in visual editor is quite simple: select Insert > Images and media and follow the onscreen instructions.
There is a special syntax for inserting images if you prefer to work with wiki markup rather than in VisualEditor. It allows to set look and feel, size, alignment, position, caption of your image, link it to an arbitrary page or URL.
