Can featured image come from a URL?

[jamesbraza]

I would like to use a publicly available image as the featured image for an article.

Instead of having a local file featured.png, can I reference a URL instead?

---

I know there's externalURL frontmatter parameter from https://blowfish.page/samples/external/, I am wondering if I can do something similar for featured.png

hello i find a way to use publicly picture , you can add ccoverimage: /images/featured9.jpg in your article.

and you need copy blowfish theme's one directory to you site's directory

and this is the card.html i changed

{{ $disableImageOptimization := .Page.Site.Params.disableImageOptimization | default false }}
{{ with .Params.externalUrl }}
<a href="{{ . }}" target="_blank" rel="external" class="min-w-full">
  {{ else }}
  <a href="{{ .RelPermalink }}" class="min-w-full">
    {{ end }}
    <div class="min-h-full border border-neutral-200 dark:border-neutral-700 border-2 rounded overflow-hidden shadow-2xl relative backdrop-blur">

      {{ if .Params.ccoverimage }}
        
      <div class="w-full thumbnail_card nozoom" style="background-image:url({{ .Params.ccoverimage }});"></div>

      {{ end }}

      {{ if and .Draft .Site.Params.article.showDraftLabel }}
      <span class="absolute top-0 right-0 m-2">
        {{ partial "badge.html" (i18n "article.draft" | emojify) }}
      </span>
      {{ end }}

      <div class="px-6 py-4">

        {{ with .Params.externalUrl }}
        <div>
          <div
            class="font-bold text-xl text-neutral-800 decoration-primary-500 hover:underline hover:underline-offset-2 dark:text-neutral">
            {{ $.Title | emojify }}
            <span class="text-xs align-top cursor-default text-neutral-400 dark:text-neutral-500">
              <span class="rtl:hidden">&#8599;</span>
              <span class="ltr:hidden">&#8598;</span>
            </span>
          </div>
        </div>
        {{ else }}
        <div class="font-bold text-xl text-neutral-800 decoration-primary-500 hover:underline hover:underline-offset-2 dark:text-neutral"
          href="{{ .RelPermalink }}">{{ .Title | emojify }}</div>
        {{ end }}

        <div class="text-sm text-neutral-500 dark:text-neutral-400">
          {{ partial "article-meta/basic.html" . }}
        </div>

        {{ if .Params.showSummary | default (.Site.Params.list.showSummary | default false) }}
        <div class="py-1 prose dark:prose-invert">
          {{ .Summary | emojify }}
        </div>
        {{ end }}
      </div>
      <div class="px-6 pt-4 pb-2">

      </div>
    </div>
  </a>

you might want to wrap that differently. check out the hugo docs for 'resources.GetRemote'..

{{       with resources.GetRemote ($.Scratch.Get "name")  }}
{{/*        The named file matches a fetchable remote resource */}}
{{-         with .Err }}
{{-           errorf "%s" . }}
{{-         else }}
{{-           $.Scratch.Set "source"  . -}}
{{-         end  -}}
{{-     end -}}

and can then eval scratch.Get 'source' later in yer template to optionally preset the asset.
