Anyone gots a primer on doing it right?

Example:
[img]index.php?page=RGalleryImageWrapper&itemID=323&typ e=page[/img]

When I click the "Insert MonkeyPr0n" button and paste in the hyperlink (or image location link) to a pic I uploaded to the gallery, all I gets is the raw [img ] tag. Or am I the only one that doesn't see the image as...an image?
