I've put a library of various buttons, balls, lines, ... etc on the exp tree under directory /exp/rcf/common/X11R5/lib/icons/AIcons/images. You only need to create a symbolic link to the directory under your ~/public_html. For example:
cd ~/public_html ln -s /exp/rcf/common/X11R5/lib/icons/AIcons/images imagesThen you can use all the images under that directory by referring to the icon on the exp tree. Or If you prefer, you could also copy the ones you like to your own directory instead of the links.
You could check out the Images.html under that directory for details.
