There are a number of FTP and web sites with Scouting clipart images
which you can use.  I have tried to maintain an up-to-date listing of
them at

The use of these images probably falls under the rule of "it's OK 
because you are using them to promote Scouting."  But, I'm not a 
lawyer, so if asked to remove them, it's probably a good idea to 
comply.  As long as you use them in a manner consistent with the 
Scouting ideals and not in conjunction with some unScout-like themes,
you are probably OK.
