[Feature Request] Update media sizes metadata in media translation duplicates

Hi Andreas,
if you mean the Regenerate thumbnail plugin I tested it and discarded because I was not sure how it works since the WP 5.3 update. I found it generates unnecessary thumbnails in the form of name_scaled-withxheight.jpg etc. That's why I became interested in native image regeneration support, which is reliable even for sites with a large number of images like ours. Using the WP CLI seems to me to be the ideal choice. I would definitely recommend including functionality in WPML that somehow accounts for resizing thumbnails. I've tried manually regenerating the translation image, e.g. WP MEDIA REGENERATE 1255, but even then the POSTMETA table entry is not updated and the WP CLI handles the original file by default.
So in its current form, WPML does not even support changing themes, as this is usually associated with changing thumbnail sizes as well.

However, maybe your colleagues can advise me on some magic SQL statement that will ensure that the updated POSTMETA size data of existing thumbnails is transferred to their translation copies without overwriting the translated text in them.

Otherwise there's nothing to debug here, I'm really only referring to the basic functionality of WP and WPML. If your way of translating media can be considered an ideal standard, perhaps WordPress itself could support it instead. But I don't know how other translation plugins work.

If you need, I can export and attach a sample of non updated field from wp_postmeta.

With best regards,
Jiri

Can't we come up with some SQL statement that would handle this once? BTW, I was doing a database inventory and found inconsistencies with some attachment file posts whose TRID was tied to a page type attachment. I could tell you what's going on under the hood of our WPML...
