Thanks, I understand the concern – the plugin has a setting that allow you to configure how many Giphys to load at a maximum, so it shouldn’t be too much of an issue on the client-side rendering.
As for the server-side, if I’m not mistaken this is just a integration to add an img tag, so it shouldn’t be too heavy.
I might be wrong, but I think there’s a real possibility that this does not impact performance too much. But I understand if you still think it’s not a good idea.
