Automatically crop all rectangles

[panasonik]

I have a png file with, say, a lot of rectangles.
Is there any way I can automatically crop all these rectangles to separate image files?

Thanks

use the slice tool under the crop tool click and drag it around each rectangle then go to file save for web and make sure you select images no need for images and html create a new folder and click save it will make several images in that folder on each slice you make.
