When you want to share a image you found on PieFed, don’t download and share the image, just share the PieFed link.
This way the people or person you’re sharing it with might discover PieFed without you pushing it.
It also works great like this https://www.reddit.com/r/AskTheWorld/comments/1md2npo/what_is_the_best_power_outlet_and_why
(does not work with old.reddit )
This will also improve SEO, and PieFed etc. might start popping up on search engine results more, and people will start to see and trust the Fediverse more.

Good luck.
