A way to download only first or first x images [Feature Request]

[JilekJosef]

Hi,
could you please add option to download x amount of images in single post at most. When downloading it takes sometimes really long when a single post contains 50+ images, I would like to have a way to limit amount of images downloaded per post as when creating datasets you need a diversity and since these images are usually variations it would be faster to just not download them. As well a way how to exclude ugoira and download illustrations only would help.
