Doesn’t work well with -scaled images

WordPress scales down very big images, adding a ‘full’ image with ‘-scaled’ suffix, and stores the original file and it’s name in the db. RT plugin however regens thumbails based on the ‘scaled’ image, so all the intermediate sizes are re-named. This can break images when combined with offloading etc.

Unless I am missing something, this ‘-scaled’ resizing of big images is default wordpress functionality so the RT plugin should handle it properly by using the original image (using functions like wp_get_original_image_url, wp_get_original_image_path) etc, so as not to orphan a whole set of thumbnails, use the wrong full image and generate a new set of intermediate sizes.

Eg:
These are the currently registered thumbnail sizes, whether they exist for this attachment, and their filenames:

• thumbnail: 280×178 pixels (cropped to fit) 8C2A3575-scaled-280x178.jpg
• medium: 300×300 pixels (proportionally resized to fit inside dimensions) 8C2A3575-scaled-300x200.jpg
• medium_large: 0×0 pixels (thumbnail would be larger than original)
• large: 720×1200 pixels (proportionally resized to fit inside dimensions) 8C2A3575-scaled-720x480.jpg
• avatar: 180×180 pixels (cropped to fit) 8C2A3575-scaled-180x180.jpg
• 1536×1536: 1536×1536 pixels (proportionally resized to fit inside dimensions) 8C2A3575-scaled-1536x1024.jpg
• 2048×2048: 2048×2048 pixels (proportionally resized to fit inside dimensions) 8C2A3575-scaled-2048x1366.jpg
• featured-medium: 700×446 pixels (cropped to fit) 8C2A3575-scaled-700x446.jpg
• featured-large: 1398×1398 pixels (proportionally resized to fit inside dimensions) 8C2A3575-scaled-1398x932.jpg
• extra-large: 1598×1598 pixels (proportionally resized to fit inside dimensions) 8C2A3575-scaled-1598x1066.jpg

The attachment says it also has these thumbnail sizes but they are no longer in use by WordPress. You can probably safely have this plugin delete them, especially if you have this plugin update any posts that make use of this attachment.
