$display_type not being properly set in jquery_slideshow

On line 41 of the module, you have:

$display_type = $teaser ? 'teaser' : 'full';

But there is no $teaser variable set in the function. I believe the code you want is:

$display_type = ($a3) ? 'teaser' : 'full';

I'd offer a patch, but first want to make sure that this really is a bug.

BTW: great module. I'm working on something very similar. I picked up some great ideas from your code. Thanks!
