New gifs need to be uploaded as the file standard for grid images are 32x32. In its current state, they are blurry and do not look good on the page. I have left them on the page for now and if they are not replaced soon, they will be removed from Essence and replaced with a single item type with a note explaining the rest of the recipes.
Also, as a note: The timing on GIFs on a website may not work as intended due to the way pages load. They can be out of sync a majority of the time depending on the users internet connection and how their browser is set-up. Presently there is no way to solve this issue on this wiki. Just be cautious of this and don't over use animations that cannot be properly synced.
Here are links to the images that need to be changed to 32x32:
