Thanks for your donation for NextGEN Gallery Optimizer Premium!
I'm afraid breadcrumb navigation in NextGEN gallery (or lack thereof) really isn't related to Optimizer, which is an add-on to help speed up your site by only loading NextGEN's scripts and styles where a gallery shortcode is present.
This really should have been posted at the NextGEN Gallery review page, or ideally, it would have been better to submit a feature request instead.
That said, I'd be more than happy to help you customize NextGEN Gallery to get the breadcrumb navigation you're after. I'll just need some further information about your album/gallery structure. Do you have a live url, at all? If you'd prefer it remain private, you can email me here.
