This changes our approach from one where `srcset` and `sizes` are written to the image markup in post content to one where the responsive attributes are added on the front end when the page is being rendered. There is a small performance hit but the benefit is worth the tradeoff for what is gained. What exactly do we gain? Glad you asked: * Automatically extend support to images in posts published before we responsive image support was available. * Removes the need to update the markup in TinyMCE when the image size is changed. * Keeps `sizes` attributes, which should probably be adjusted based on the needs of the theme, from being stored in the database. * Is non-destructive if a site needs to change available image sizes and regenerate thumbnails. Changes: * Removes the old JS code for handling markup changes in TinyMCE * Adds `tevkori_filter_content_images()` as a display filter. * Adds `_tevkori_filter_content_images_callback()` to process filtered images. * Adds tests

There was a problem hiding this comment.
I am not sure but when I look at this regex it appears to me that the first group will contain everything up to the first > that it finds. So if there is a space and slash before the closing tag, it will be included.
Shouldn't we remove [\s?][\/?] and then change line 418 from
$image_html = "<img " . $atts . " " . $srcset . " " . $sizes . " />";
to
$image_html = "<img $srcset . " " . $sizes . " " . $atts . ">";
?
The space and the slash will be part of $atts.
Or am I wrong?
