How do you add those blinkes that teleport u to groups?

I'm not exactly sure what you mean because i haven't seen any blinkies like that, but if you mean what i think you do, you would have to wrap an anchor tag around the image tag that contains your blinkie

so it would look like this.

<a href="https://groups.spacehey.com/reclaiminginternet"><img src="https://file.garden/Z0fWYggQRCGWEQC9/blinkiesCafe-PG.gif"/></a>

The <a> tag would have the page you're trying to redirect to. This example redirects to the group called reclaiming the internet but it should work with any other group.

I hope this helps.
