PDF Thumbnails in Media Library Don't Fall Back to Full Size

[daleharrison]

When previewing uploaded files in the Media Library, image thumbnails fall back to displaying the full size image when the option medium_size_h is set to 0 (the 0 setting is used to stop WordPress generating thumbs at that size).

The same functionality does not work for uploaded PDFs, instead displaying wp-includes/images/media/document.png in their place. The full-size thumbnail is generated, but not used.

The Attachment Details modal window successfully falls back to the full size image when previewing a PDF under the same circumstances.

Example of PDF Thumbnail Compared to Image Thumbnails in Media Library

This was discussed in a recent Media component meeting and we suspect that the fallback just needs one more step between medium and default pdf icon to include the full thumb after no medium found.

This ticket was discussed during the recent bug scrub. It looks like it's unlikely that work will be done on this during the 6.2 cycle.

@antpb Is this still possible to land in 6.2, or should it be moved to Future Release for now?

[joedolson]

Moving this to 6.3; @antpb hasn't had the time to tackle it during this cycle, but we still think this should be fixed soon.

This ticket was discussed during bug scrub and due to lack of patch it was decided to move it out of the current 6.3 milestone. Seeing that @antpb wrote that working on it, I am moving this to 6.4.

Ad props to @mukesh27

Noting here that @antpb confirmed a few weeks ago that this would be addressed for 6.4. We're ~2 weeks from RC1 so just let us know if that is unlikely to happen by then.

I'm still pending a patch on this one and need to move to 6.5
