(not original commenter sorry for their wording) I would suggest using catbox.moe personally, and i dont particularly like that hosting site due to the adds and difficulty going from image to image.

Alternatively you could post the captions either all embeded in one post following the pinned “how to create a gallery post” or you could just post em individually that would let you get more upvotes too :p

Anyway thanks for bringing content to the community!
