Yes, which is what I thought you wanted. So, you have something like:
Slideshow <->> SlideshowToImages <<-> Image
Correct? If so, you can essentially do the same thing:
dataContext.deleteObjects(slideshow.getSlideshowToImages());
Just make sure you don't cascade delete your images from the
many-to-many join.

But wouldn't the call to
dataContext.deleteObjects(slideshow.getImages()); actually delete the
image records from the image table (upon commit). All I'm trying to do
is clear the relationship table, because any given image form part of
any number of slideshows. Hence I don't want to delete the actual
images just the link (record in join table) between Slideshow & Image
