## History
We used to pass `onLoad` through directly to the underlying img so `onLoadingComplete` was introduced in order to handle the case when `placeholder="blur"` was used and `onLoad` would trigger before the placeholder was removed.
We have since changed the behavior of `onLoad` so that it acts the same as `onLoadingComplete` and therefore `onLoadingComplete` is no longer needed.
## What is this PR doing?
This PR marks `onLoadingComplete` as deprecated in favor of `onLoad`. In the future, we may remove `onLoadingComplete`.
Added an image gallery example using Next.js and Cloudinary.
Edit: This is now ready to ship!
