Consider exporting your content out of the old WP version and into the new one with the built in WP tools (under ‘Tools’ in the admin dashboard. Make sure you have the export images box checked.

You may need to reset the thumbnail settings in your media settings, then regenerate the thumbnail; either: use Regenerate Thumbnails plugin to rebuild all thumbnails; or edit image / rotate it left / rotate it right (back to original) / save image
You can pest following code in function.php. add_theme_support(‘post-thumbnails’); add_image_size( $name, $width, $height, $crop); add_image_size(‘Home Top’, 120, 120, true); add_image_size(‘Home bottom’, 270, 90, false); add_image_size(‘Archive thumb’, 150, 75, true); add_image_size(‘Special’, 397, 224, true); add_image_size( ‘Test cropped’, 500, 500, true ); function sgr_display_image_size_names_muploader( $sizes ) { $new_sizes = array(); $added_sizes = get_intermediate_image_sizes(); foreach( $added_sizes as $key => … Read more
As written in the documentation, there are no attributes width and height in the fourth parameter of the function. What you might want to do is this: wp_get_attachment_image( $id, array( 10, 10 ) ); An alternative and recommended way is to define an image size which will lead WordPress to generate a thumbnail for this … Read more
Have a look at wp_get_attachment_image_src <?php $attachment_id = 8; // attachment ID $image_attributes = wp_get_attachment_image_src( $attachment_id, ‘medium’ ); // returns an array if( $image_attributes ) { ?> <img src=”https://wordpress.stackexchange.com/questions/169475/<?php echo $image_attributes[0]; ?>” width=”<?php echo $image_attributes[1]; ?>” height=”<?php echo $image_attributes[2]; ?>”> <?php } ?> Source: http://codex.wordpress.org/Function_Reference/wp_get_attachment_image_src#Default_Usage
It appears that the thumbnail URLs are generated relatively to the upload folder. So trying to store them outside the uploads folder is not going to be a good idea. There are hacks to filter the output for functions such as the_post_thumbnail_url(), but considering side issues such as the thumbnails not being able to be … Read more
To remove all extra image sizes you use get_intermediate_image_sizes() in tandem with remove_image_size(). E.g. function remove_extra_image_sizes() { array_map( ‘remove_image_size’, get_intermediate_image_sizes() ); } add_action(‘init’, ‘remove_extra_image_sizes’); To edit the image size dropdown you can hook a custom function to image_size_names_choose filter. function filter_image_size_names_choose($size_names) { return array_filter( $size_names, function( $size_name ){ return ‘full’ === $size_name; }, ARRAY_FILTER_USE_KEY ); … Read more
add_filter(‘intermediate_image_sizes_advanced’, ‘filter_image_sizes’); function filter_image_sizes( $sizes) { unset( $sizes[‘thumbnail’]); unset( $sizes[‘medium’]); unset( $sizes[‘large’]); return $sizes; }
I found the same issue here and the solution from there works. The solution is as simple as pasting this: $content_width = 2000;// Value higher than your new ‘large’ width in functions.php Explanation copied from there(user Chip Bennett): I believe your issue is that the value set for the global $content_width variable (which is 640px … Read more
Figured it out after a lot of trial and error and a lot of var_dumps. $image = wp_get_image_editor($file); if ( ! is_wp_error( $image ) ) { $image->resize( $width, $height, true ); $final_image = $image->save( $file ); } Then i can use the $final_image array to get what i need. It actually saved me a step … Read more
