There is no way to base the image sizes on the post type, as images are not yet attached to a post when you upload them and the intermediate image sizes are created (when you just add them via “New Media” they are not even attached to any post at all). However, I recently created … Read more
To built on Max Yudin’s answer you should use the intermediate_image_sizes_advanced filter, and not image_size_names_choose. Add to functions.php function add_image_insert_override($sizes){ unset( $sizes[‘thumbnail’]); unset( $sizes[‘medium’]); unset( $sizes[‘large’]); return $sizes; } add_filter(‘intermediate_image_sizes_advanced’, ‘add_image_insert_override’ ); Another easier option I think works is going to your Settings–>Media and setting each box for width and height to 0
Add this code to your theme’s functions.php file, and it will limit minimum image dimentions add_filter(‘wp_handle_upload_prefilter’,’tc_handle_upload_prefilter’); function tc_handle_upload_prefilter($file) { $img=getimagesize($file[‘tmp_name’]); $minimum = array(‘width’ => ‘640’, ‘height’ => ‘480’); $width= $img[0]; $height =$img[1]; if ($width < $minimum[‘width’] ) return array(“error”=>”Image dimensions are too small. Minimum width is {$minimum[‘width’]}px. Uploaded image width is $width px”); elseif ($height … Read more
A way to do it is to use the (very convenient) editor:image-edit and editor:image-update events triggered by the tinymce wpeditimage plugin to get/set the dom directly (updated to wrap in wp_enqueue_media action): add_action( ‘wp_enqueue_media’, function () { add_action( ‘admin_footer’, function () { ?> <script type=”text/javascript”> jQuery(function ($) { if (wp && wp.media && wp.media.events) { … Read more
I figured it out! In my php.ini file I had to uncomment extension=php_gd2.dll, then it started working after I rebuilt the images I uploaded 🙂 Thanks, Josh
I created two plugins that together should solve my needs. They are currently in an early alpha stage, and all comments are welcome. The base plugin is an On-Demand Resizer. This plugins monitors requests for non-existing files in the uploads dir, and creates images of the requested size if needed. For example, image-200×100.jpg will create … Read more
Intermediate image generation is extremely rigid. image_resize() keeps it close to code and completely lacks hooks. Pretty much only option for this is to hook into wp_generate_attachment_metadata and overwrite WP-generated image with your own (which will need bit of a image_resize() fork). I need this for work so I might be able to share some … Read more
If you have the attachment id, you can use get_the_title() $attachment_title = get_the_title($attach_id) http://codex.wordpress.org/Function_Reference/get_the_title
Take a look at Otto’s Dynamic Image Resizer plugin This plugin changes the way WordPress creates images to make it generate the images only when they are actually used somewhere, on the fly. Images created thusly will be saved in the normal upload directories, for later fast sending by the webserver. The result is that … Read more
Yes, it’s possible and pretty easy. This is the workflow I suggest: Put somewhere a UI to insert the URL of the featured image. Probably best choice is to use ‘admin_post_thumbnail_html’ filter hook Use ‘save_post’ action hook to save the URL (after security and validation routine) in a custom post meta Use ‘post_thumbnail_html’ filter hook … Read more
