It could be because with image extraction, there's a cutoff threshold. Several pages on the internet have icons, buttons, logos etc with small images in them. They are mainly intended to boost the design of the page. These small images just add too much noise in the final result, making useful images hard to find. That's why this cutoff exists.

The way this threshold works is as follows

---

Threshold for the Image extraction - Range is 1 to 6

Images are scored based on point based system, to filter based on usefulness. Points are assigned
to each image based on the following aspects.

1. If either height or width exceeds 150px
2. If image size is greater than 10Kb
3. If alt property is set
4. If image format is in jpg, png or webp
5. If image is in the first half of the total images extracted from the page

Default threshold is 2.

You can override this by updating IMAGE_SCORE_THRESHOLD constant in config file

Quickly check if you update this threshold to zero, you are able to get all the desired images, if not please reopen this as a bug.
