ai_context: "Use this article for questions about the RUMvision Image priority filter, `fetchpriority` values and whether Largest Contentful Paint (LCP) images are being requested with the right browser priority. It explains how to compare LCP images using `fetchpriority=\"high\"` versus `low`, `auto` or no explicit priority, and how the filter can reveal LCP candidates that are not being prioritized correctly. Relevant for questions about image request priority, LCP Resource Load Delay, fetch scheduling, bandwidth competition, `fetchpriority=\"high\"`, resource hints, file type, file size, cache status and diagnosing whether slow LCP is caused by request prioritization rather than the image itself."

# Image priority

> This filter works with the [Largest Contentful Paint metric](https://www.rumvision.com/help-center/glossary/metrics/largest-contentful-paint/?format=md)

The `fetchpriority `attribute can be used to boost the priority of an LCP image. You can use our image priority filter to see:

- if your site or shop still has LCP image candidated that don't have a `fetchpriority=high` attribute;
- the difference between image with and without a `fetchpriority `strategy.

Attribute values are [as following](https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Attributes/fetchpriority#high):

- [`high`](#high)  
     Fetches the external resource at a high priority relative to other external resources.
- [`low`](#low)  
     Fetches the external resource at a low priority relative to other external resources.
- [`auto`](#auto)  
     Doesn't set a preference for the fetch priority. It is used if no value or an invalid value is set. This is the default.
 
This filter can be used with resource hints, filetype, filesize and cache status filters to explain Load Delay and request scheduling/competition.
