Looks to be a problem with the images themselves. 
When inserting this into Writer I get an error message "Image filter not found".

Maybe they were made using some new encoding standard?
Comment 4 NISZ LibreOffice Team 2021-07-08 06:55:30 UTC 
file reports for the problematic 3:

$ file *jpg
image2.jpg: RIFF (little-endian) data, Web/P image, VP8 encoding, 1024x768, Scaling: [none]x[none], YUV color, decoders should clamp
image3.jpg: RIFF (little-endian) data, Web/P image, VP8 encoding, 1024x768, Scaling: [none]x[none], YUV color, decoders should clamp
image4.jpg: RIFF (little-endian) data, Web/P image, VP8 encoding, 1024x682, Scaling: [none]x[none], YUV color, decoders should clamp

@Tomaz, I recon you understand these topics better, is it possible to support such images?
Comment 5 Tomaz Vajngerl 2021-07-09 07:11:01 UTC 
These are WebP images, so this bug would be related or duplicate of the bug [1]. Until now there wasn't much need to add support for WebP images, but if you can add them into MSO, then we will have problems and will have to add support - at least for reading or we will have more problem in the future. 

What we need is to add building of external library libwebp (+ system lib override) and add reading support in vcl/source/filters + GraphicFilter class

OK in master 7.4+ after fix in bug 114532. 
I mark Fixed, although this could be also a duplicate.
