The img url helper outputs the correctly calculated URL for the provided image property. You must tell the
{{img_url}} helper which image you would like to output. For example, to output a URL for a post’s feature image inside of post.hbs, use {{img_url feature_image}}.
Force the image helper to output an absolute URL by using the absolute option: {{img_url profile_image absolute="true"}}. This is almost never needed.
To output the image in question at a resized resolution based on your theme config, pass in dynamic image sizes via the size option.
Convert an image to a different image format (webp, avif, png, jpg, jpeg, or gif) by using the format option. (This only works in combination with the size option.)
