This module was under development during the period we were all waiting for a D8 implementation of Menu Breadcrumb. I wrote this to implement the same behaviour, but while working on a second module to breadcrumb articles by taxonomy (for the common Blog use case) I realised:
The simplest way to breadcrumb taxonomy members, as in the case of multiple Blogs, is with a breadcrumb trail which continues from the Blog page's own breadcrumbs.
This module adds alts and titles for images to where they are not, taking them out of the title material. This is useful when you have no desire to prescribe alts & titles for images. You can also opt for what type of material to use these settings.
