The Gallery is a nice tool for easy access to clip art or any graphics. Here are a couple blogs on it.

Here's a tip from Dave Richards -- you can make the gallery float, so that you can position it in a more convenient place in your work area.
What the Gallery Generally Looks Like
Choose Tools > Gallery, and you get the clip art and categories on your system. (You can click on each of these images to see a bigger version.)
One of the great things about OpenOffice.org is that you can open corrupted Word files with it. Or Word files that are just too big to open in Word, open fine in OpenOffice Writer.
However, every so often you will get a rogue OpenOffice file that just won't behave. It crashes constantly, or behaves in other ways that just don't make sense.
In that case, the best approach is surgery.
