This plugin finds every GIF animation in your posts and replace it to a preview image. Doesn’t matter the GIF embedded from another website or use WordPress’s static thumbnail. It automatically generates the preview image from the first frame of the animation and save it to the post’s media directory with <code>-gap.jpg</code> suffix.
Posts show the pregenareted small size jpeg file first, your visitors don’t need to wait for download the huge animation. Play animation after they click on the image or after your whole page has downloaded. It depends on your setting:
<ul>
<li>You are able to stop animations everywhere</li>
<li>Or start animation automatically only inside a post</li>
<li>Or start the moves everywhere by default, use this plugin for lazyload</li>
</ul>
There are additional settings:
<ul>
<li>Pretty smooth effect between your preview and animation</li>
<li>Start animations with your mouse</li>
<li>Work with metadata and preview</li>
<li>Disable on certain images with <code>nogap</code> class</li>
</ul>
Don’t worry, delete this plugin will remove all settings from your database. Generated preview images gonna stay there, you can use them everywhere until you delete them manually.

Ever wanted to use gifs in your content? Look no further. GIF Master does just that with unlimited free gifs powered by Giphy and Tenor.
You will see an additional gif button in the post/page editor and clicking this will open a new popup where you can search for your favorite gifs and insert them in your content. It’s that easy!
Notice: If you are using some page builder or Guttenberg and not classic editor, you can insert a classic visual/html block and then you will see the gif button.
This plugin doesn’t generate any gif on it’s own and relies on services provided from <a href="https://giphy.com/" rel="nofollow ugc">Giphy</a> and <a href="https://tenor.com/" rel="nofollow ugc">Tenor</a> to get the gifs from these sites with attribution.
You would need to create accounts on Giphy and Tenor and get your API keys from there. Both services are free. Check their terms of service and other guidelines as below: 
Tenor – <a href="https://tenor.com/legal-terms" rel="nofollow ugc">Terms of Service</a> and <a href="https://tenor.com/gifapi/documentation#apiterms" rel="nofollow ugc">API Terms</a>
