<h1>Local Custom Emoji</h1>
|
|
<p>
|
|
To use custom emoji in your toots they have to be 'local' to the instance.
|
|
You can either upload them here directly, or copy from those already
|
|
present on other (known) instances through the <Link to={`/remote`}>Remote Emoji</Link> page.
|
|
</p>
|
|
<p>
|
|
<strong>Be warned!</strong> If you upload more than about 300-400 custom emojis in
|
|
total on your instance, this may lead to rate-limiting issues for users and clients
|
|
if they try to load all the emoji images at once (which is what many clients do).
