If I CFRelease() an image in core data, how do I get it back?

core-data

My iphone app plays a slide show made up of 5 user images. These images are stored using core data. I was noticing that memory was building up every time a different slide show was played and it was not releasing any of the previously played slide shows. These images are showing up in Object Allocations as CFData. So I tried releasing this data in the dealloc method

CFRelease(slideshow.image1);
CFRelease(slideshow.image2);
CFRelease(slideshow.image3);
CFRelease(slideshow.image4);
CFRelease(slideshow.image5);

This releases the previous slideshow great...BUT when I go back to view that same slideshow again, it crashes. I am guessing that I need to alloc/init these images again, but I am not sure how? Or maybe I should be managing this memory in a different way?
