It is also possible to do it in Photoshop using Slices. Basically you select the slice tool, drag a window on top of the areas you want to export, and use "Export to Web".

The way I would go about this in GIMP:


Use the fuzzy select tool (magic wand) to select the shape you need
Go to Image > Crop to selection
Export (ctrl-shift-e)
Undo (ctrl-z), start over


This takes me about two seconds per shape. Of course, fuzzy select works best with flat object in a single colour. If you've got more complex forms, it might be a bit harder to do.



Alternatively, if the images are aligned along a grid, you could use one of the methods described in this post.



EDIT: found a similar question over at superuser, seems the accepted answer over there is the one you're looking for if you really want to automate the whole thing.
