If you are just promoting another website, decline payout when you post. You are still trying to profit from another site's work and profit at the expense of original content creators. It's just bad netiquette.
You could instead post a single image and a personal description of why people should visit the host site. Treat it as a review of their product. That would be far more in line with legal and moral fair use, plus a better fit with Steemit culture.
Ok thanks for the reply : )
