Making error message clearer

You should be coding defensively.

A simplified example (ignores alt and title attributes):

{{ $r := "" }}
{{ with .Page.Resources.Get .Destination }}
  {{ $r = . }}
{{ else }}
  {{ errorf "The image render hook was unable to get image %q." .Destination  }}
{{ end }}

{{ with $r }}
  {{ with .Fill "400x200 webp q50"  }}
    <img src="{{ .RelPermalink }}" width="{{ .Width }}" height="{{ .Height }}" alt="">
  {{ end }}
{{ end }}

If the image isn’t present, processing stops, and you will never get to the image processing bits.
