iis server blocking access to .webp files

So I'm trying to add .webp image support, which is run on iis.

now the image exists on the server and the file name is correct but when I try to load the image via url address in the browser I get the 404 error.

    404 - File or directory not found. The resource you are looking for might have been removed, had its name changed, or is temporarily unavailable.

It's beter add this config to your webconfig file

<configuration>
<system.webServer>
<staticContent>
<mimeMap fileExtension=".webp" mimeType="image/webp" />
</staticContent>
</system.webServer>
</configuration>
