Notes and Resources for Responsive Images in WordPress 4.4

Following the addition of responsive images support in WordPress 4.4, there has been a lot of confusion over what WordPress does "automatically" and what is left up to the developer. I've gathered the following notes from chatting with members of the core team and also my own investigation of the 4.4 source. Here's what I've discovered:

• Following the 4.4 update, WordPress automatically serves the following images responsively:

  • Content images added via the main content editor will now be served with srcset markup. This is accomplished by filtering the_content() prior to display, which means it applies to existing posts and new posts going forward.
  • Featured images called by the_post_thumbnail() also get srcset markup without any additional steps required.

• Images that are referenced from custom fields will not be served responsively unless the theme calls the image via wp_get_attachment_image() OR constructst the responsive m

/*
- I have a CPT named Galleries and within this CPT there are 6 individual galleries, all using the same format.
- I have used the Enhanced Media Library plugin to allow a category(ies) to be added each image uploaded.
- single-galleries.php - is a template used for displaying each of these individual galleries.
- Each individual gallery has aprox 4 categories in use that are assigned to the different images.
- There are aprox 24 categories for all of the images across the 6 individual galleries(1-2 per image)

Problem: code for "gallery-filter" below is currently echoing out ALL(~24) media categores.

Solution needed: for only those categories acutally used on the page (rememeber 6 diff galleries)
