I'd like to write a program in Perl utilizing the Yahoo API and Yahoo-Search module for extracting links from their image search engine, and then automate downloads of the thumbnail image search results with the Perl LWP module. Does anyone know if such a program violates Yahoo's terms of service and if a perl module exists for already doing this? I see there's already a program that does something similar with Google's search engine called Googlegrab at http://www.sas21.de/apps/googlegrab/ .
