Random Images in Drupal 6

I have Drupal 6 and noticed a Random Images Block when editing blocks.

I was wondering whether it is possible to specify what directory to get the random images from so that I can display only the images I wish to display.

Also wondered about other settings like linking the images to specific pages instead.

I looked on drupal site and found a random image module but this is for version 5 (downloaded and tried but it does not work in version 6)

I have not downloaded a module for Random images for version 6 yet I have the block and I like what it does except I would like the ability to specify which images it uses.
