Yes, you can do that with Web Dumper as well. It is known as 'Incremental Download'.Indeed, you can fetch contents by enclosing sequence numbers into brackets directly into the URL. For example:
www.maxprog.com/picture[12-15].jpg
will have Web Dumper to download 'picture12.jpg' to 'picture15.jpg' that is:
http://www.maxprog.com/picture12.jpg
http://www.maxprog.com/picture13.jpg
http://www.maxprog.com/picture14.jpg
http://www.maxprog.com/picture15.jpg
You can insert more sequences like in:
www.maxprog.com/test[1-2]/picture[001-002].jpg
resulting in the files 'picture001.jpg' and 'picture002.jpg' from the folders 'test1' and 'test2' to be downloaded from:
http://www.maxprog.com/test1/picture001.jpg
http://www.maxprog.com/test1/picture002.jpg
http://www.maxprog.com/test2/picture001.jpg
http://www.maxprog.com/test2/picture002.jpg
The possibilities are endless, you can fetch whole image libraries or any kind of file (html, movies, etc…) in a blink. If you need more information about that feature dont' miss this tutorial.
