Lightbox 2 and Flash_Gallery

Hello. Drupal n00b here.

I have taken over managing a website, www.fenariogallery.com
This site is an art gallery, and thus uses the Lightbox 2 module to display images.

I have been asked to replace Lightbox 2 with Flash_Gallery + Simpleviewer.

I have installed the Flash_Gallery + Simpleview module, and activated it from the
/admin/content/fgallery menu, As well as de-activated lightbox 2. I have noticed that the two do not seem to deliberately affect eachother.

I am not familiar with editing web-content and functionality through a CMS such as Drupal. The options for configuration seem overwhelming.

So do i need to move or copy all folders of pictures from 'image galleries' to image folder in the flash-gallery or simpleview sub-directories?

I know i am probably over-complicating this issue. Some guidance or help would be
greatly appreciated.

thank you for your consideration.
