How does your code know if you've called drawImage on object g before?
You might be passing in different g objects with each paint() call?

If you wish to load the gif only once, can't you do that in the init()
method?  (I'm not applet savy, perhaps there's a reason why you can't
load it in the init, but I have to ask anyway.)

Perhaps you want to create and draw into that buffer only once, in the
init(), and simply repaint it onto every g object?

Hrm.  I don't think you can really do this.   I think your paint()
method is supposed to assume that its entire coordinate space has
been erased and it needs to rebuild it all.  You have to redraw
the whole image every time.
