With this project structure:

        ├── e.avif
        └── f.jpg

These are the values returned by the reflect.IsImageResource function:

{{ with resources.Get "a.json" }}
  {{ reflect.IsImageResource . }} → false
{{ end }}

{{ with resources.Get "b.avif" }}
  {{ reflect.IsImageResource . }} → false
{{ end }}

{{ with resources.Get "c.jpg" }}
  {{ reflect.IsImageResource . }} → true
{{ end }}

In the example above, the b.avif image is not a processable image because Hugo can neither decode nor encode the AVIF image format.

{{ with .Resources.Get "d.json" }}
  {{ reflect.IsImageResource . }} → false
{{ end }}

{{ with .Resources.Get "e.avif" }}
  {{ reflect.IsImageResource . }} → false
{{ end }}

{{ with .Resources.Get "f.jpg" }}
  {{ reflect.IsImageResource . }} → true
{{ end }}

In the example above, the e.avif image is not a processable image because Hugo can neither decode nor encode the AVIF image format.

{{ with site.GetPage "/example" }}
  {{ reflect.IsImageResource . }} → false
{{ end }}
