integrating simple image gallery into a m simple joomla web page

I have a simple joomla based webpage, where I would like to integrate the simple image gallery. I would give you access to that joomla installation and ask you to place that plugin an one of the webpages. After that, I would like you to explain to me, what you did, so hopefully in the future, I can do it myself. I am aware, that there are easier and nicer galleries for joomla, but since I have a webcamera uploading images every x minutes in one folder, I would like the gallery to update itself all the time and add the new images. The simple image gallery is the only gallery I know, that automatically displays the images from a complete folder.
