One of the default screensavers included with Ubuntu 7.10 is one that will display whatever pictures you have saved in your ‘Pictures’ folder (/home/<username>/Pictures). The screensaver will randomly display a picture from this and any subfolders.

However, there’s no way of customsing which folder the screensaver reads if you want to use your Pictures folder to store pictures, but manage which of these images is used.

A workaround is as follows:

• Create a new folder somewhere (it doesn’t have to be under the ‘Pictures’ folder)
• Open a terminal window (select Terminal under Accessories)
• enter the following:

  gksu gedit /usr/share/applications/screensavers/personal-slideshow.desktop

  (enter your password if prompted)

• Scroll down to the line (near the end) that begins

  Exec=slideshow

• Add the following after this command:

  --location=<your pictures path>

  (You will have to use standard escape sequences if you have spaces in the path.)

• Here’s an example:

  Exec=slideshow --location=/home/myusername/Pictures/My\ Screensaver

And that’s it. Save the file, and restart your screensaver. It will now only search for pictures in your chosen folder.
