This can be done using block filters. First, you’ll need to filter block attributes for the image block to be able to save the new items: const { addFilter } = wp.hooks; function filterAttributes( settings, name ) { if ( ‘core/image’ === name && settings.attributes ) { settings.attributes.description = { type: ‘string’, default: ” }; … Read more

I suggest to check out Get the Image plugin. Basically it is single function that acts as flexible and configurable wrapper to mine posts for images via different methods (post meta fields, featured images, attached images, images in post body).
You can use this plugin: http://wordpress.org/extend/plugins/regenerate-thumbnails/.
The image_send_to_editor hook passes a whole range of parameters, not just the html. One of them is the size. To get it, hook your filter passing an 8 as the number of supported parameters: add_filter(‘image_send_to_editor’, ‘my_filter_cb’), 10, 8); and modify your function header to grab them all: function my_filter_cb ($html, $id, $caption, $title, $align, $url, … Read more
So it looks like I found one. SB Uploader. Now I need to figure out how to use it in my theme. The get_post_meta is a little fuzzy to me
Just add this scripts in header <script src=”http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js”></script> <script> var blank=”http://upload.wikimedia.org/wikipedia/commons/c/c0/Blank.gif”; function readURL(input) { if (input.files && input.files[0]) { var reader = new FileReader(); reader.onload = function (e) { $(‘#img_prev’) .attr(‘src’, e.target.result) .height(100); }; reader.readAsDataURL(input.files[0]); } else { var img = input.value; $(‘#img_prev’).attr(‘src’,img).height(200); } $(“#x”).show().css(“margin-right”,”10px”); } $(document).ready(function() { $(“#x”).click(function() { $(“#img_prev”).attr(“src”,blank); $(“#x”).hide(); }); }); </script> … Read more
wp_upload_dir() is perfect. It is the only place where you can expect write permissions. Store the attachment ID, not a path. Then you get the image with: wp_get_attachment_url( $attach_id ) Sometimes a user may have deleted the image per media library. To avoid problems with missing files check the return value from wp_get_attachment_url() first. Excerpt … Read more
imagecreatefrom* functions return an image resource identifier, which when cast to a string (saving an option) will result in an empty string(0) “” container. Raw images created by these functions do not have any specific data structure that can be serialized out of the box. Two solutions I can think of: image files Use imagepng, … Read more
I developed a plugin that does that. It creates the new images for you (with @2x), tells you if the original image is not big enough (and give you a ‘Reupload’ button), then serves it to the clients using two methods (a image handler or a script). Please try it and tell me if I … Read more
