First of all, you need to upload a picture to the wiki via Special:Upload. Then for adding it to the page, that depends on how you want to add it.

If you have an infobox, which you should do for making a creature page, there's usually an image field you put the file name into, either via a form (if you're using a form) or manually (by adding e.g. |image=Behlah.png into the code).

If you're adding an image outside of an infobox, the full code is, for a file titled "Behlah.png" and with a desired image width of 300px.
