It can also be optimized if merged with some more programming and the the code merge all the images and output a pdf file instead. :)

Useful tool. If this wasn't there, I'd have to take a screenshot every page and save it. So, I'm really thankful for this.

So far it works, I am currently downloading a PHP 5 book to learn PHP5! Goo userscripts and google!

Hi Redphx,

I would like to thank you for this script, because in my country books are very very expensive.
Congratulations for your script, but Google Book changed and this script don’t work as before (don’t find the pages).
I think that we need to wait for new version.

...especially about downloading all the pictures. It could make a list of URLs for Orbit Downloader, for example.

This is a time saver and works well with the current version of FF.

I've always found this script good, but I note there appears to be a version 2.3 modified by a different author here:

At a cursory glance it seems pretty similar, just with a few new tweaks

I tried to take this book:
http://books.google.com/books?id=8Z23c2F7ZHcC
But at first, it can only take 160 pages of the book. I tried to move to the middle of the book and run it again then it can take 600 pages but it just ran through 50 pages and stopped there.

One more thing is when using Internet Download Manager to download, the file names become books_1 books_2 and it break the order. So which download manager should I use to keep the names of the pages like PR1 PR2?
