As you will now see in the edit bar, we have a dedicated Giphy button (seen below). Simply click on that, search for a gif you want and the site does the rest. This button (should) be available across all formats of the site. I have it set up to embed as an image rather than media, so no more broken Giphy embeds if you choose to let the site handle it by simply posting a link (which only works 50% of the time). Enjoy.
