I would like to change the image sizes for "medium" and "large".
I did change the sizes in Settings > Media
This however does not seem to have any effect on the settings I see when I edit or insert an image:
I did empty cache and reset the browser.
I also changed the theme's settings for the custom image size and content_width accordingly – but this does not have any influence on what options are displayed under Image Details.
add_image_size('full-width', 1600, 0, false);
if ( ! isset( $content_width ) ) $content_width = 1600;
Now I'm stuck – would appreciate any pointer… Thanks!
PS: I know there are plugins like Simple Image Sizes that could be handy – but I would like to try to do this 'the right way' (if that makes any sence).
