After this, you have the original image split in a lot of imagettes:

And you have to save - pardon, export - each of them with a proper name.

Ok, maybe you can use a script for the guidelines and apply the slice plugin (which saves the pictures in a folder) to make it faster...

In Inkscape you can choose the area to export, and you can simply calculate the proper coordinates and save each image:
