No, using a custom image loader does not remove the use of the cache in the <Image> component. The image loader is primarily responsible for generating the URL of the image, while caching behavior is handled separately.

According to the Next.js Image Component documentation, a custom loader is a function that returns a URL string for the image, given parameters like src, width, and quality. It doesn't directly affect caching.

The caching behavior for images is determined by other factors, such as:

1. For local images, the cache key is based on query string parameters, the Accept HTTP header, and the content hash of the image URL, as mentioned in the Vercel Image Optimization documentation.

2. The minimumCacheTTL configuration in next.config.js can be used to set a minimum cache duration for optimized images, as described in the Next.js Image Component documentation.

3. The Cache-Control header of the upstream image also plays a role in determining the expiration of the optimized image.

It's important to note that while you can customize the image URL generation with a loader, the caching mechanisms remain in place to ensure optimal performance of your Next.js application.
