I don't understand how to customize responsive sizes images in WP 4.4.1.
The only available hooks that I see are
wp_calculate_image_sizes, and neither has the named image size that was asked for as a parameter. So that would mean that you can correct image sizes, but with no knowledge of the context?
One simple case, with one banner and 3 image sizes :
- Mobile (780x200)
- Tablet (980x250)
- "Desktop" (1600x300).
What I want is to be able to tell WP core that I want those dimensions at width w1, w2 and w3 (which would be here 0-780, 781-980 and 981+), or that I want the named image size mobile for w1, tablet for w2 and desktop for w3.
Anyone have a clue?
