Here are a couple of small improvements:

1. The final back-reference is not necessary for the extraction of the 
search term so it may as well be left off.

2. An additional REFALIAS in front of the original one will merge most 
(but not all) of the quoted search-terms with their corresponding 
unquoted terms. Probably, even better results could be achieved with a 
regular-expression, I'll look into that in future.

So what I'm using now is this:

REFALIAS 
http://images.google.*/imgres?*&prev=/images%3Fq%3D%2522*%2522%26* 
http://images.google.$1/images?q=$3&
REFALIAS http://images.google.*/imgres?*&prev=/images%3Fq%3D*%26* 
http://images.google.$1/images?q=$3&
SEARCHENGINE http://images.google.*/* q

(Each REFALIAS on one line with spaces where the linebreaks are above.)

Thanks again Marcel.
