Hi,

see:
http://root.cern.ch/cgi-bin/print_hit_bold.pl/root/roottalk/roottalk00/0402.html?gifbatch#first_hit

You can have a look at the roottalk discussions on this subsject.
Go to the root search engine (or Google) and search, eg for
  gif batch

The Root search engine is at: http://root.cern.ch/root/Search.phtml
