It would likely be fetched with a high priority in this case anyway, so this combination should not really be needed nor used. Note that an image with loading="lazy" and fetchpriority="high" will still be delayed while it is off-screen, and then fetched with a high priority when it is nearly within the viewport. If you want to increase the fetch priority of an important image (for example the LCP image), then Fetch Priority should be used with fetchpriority="high". eager just implies the usual eager queueing browsers use by default. It does not imply that the image is loaded any quicker than another image without the loading="eager" attribute.īrowsers prioritize resources based on various heuristics, and the loading attribute just states when the image resource is queued, not how it is prioritized in that queue. The eager value is simply an instruction to load the image as usual, without delaying the load further if it is off-screen. Relationship between the loading attribute and fetch priority While this is the default, it can be useful to explicitly set this if your tooling automatically adds loading="lazy" if there is no explicit value, or if your linter complains if it is not explicitly set.Ĭaution: Images that are highly likely to be in-viewport, and in particular LCP images, should not be lazy-loaded.
