Hey Tess, when you make a post using the standard form (not the quick reply) you'll notice a variety of buttons/icons for things like bold, italics, underline, etc.
There are also buttons for displaying a picture (it must exist somewhere online already and you'll need the url/address of the image, it can't just be on your own computer)
There is also a Youtube icon for displaying videos as well.
