Anything else?

@bigsk1 suggested this fix in the tweet above, however I didn't want to replace the theme's version of head.html at this time

Also, after testing @bigsk1's changes in his repo, I can confirm the card now works. Tested by DM'ing myself on Twitter to (hopefully) prevent caching

[bigsk1]

The issue seems to be needing absolute url for twitter cards

<meta name="twitter:image" content="https://bigsk1.com/assets/images/bigsk1.webp">

not

<meta name="twitter:image" content="/assets/images/bigsk1.webp">

My example in head.html

Twitter Image Meta Tag: In both the {% if page.image %} and {% elsif site.social_preview_image %} sections, I added . This ensures Twitter has the correct image URL for both specific pages and the site-wide fallback.

Absolute URL for Page Image: For page.image, I've ensured the absolute URL is used by applying {{ src | absolute_url }}.

{%- capture seo_tags -%}
  {% seo title=false %}
{%- endcapture -%}

<!-- Setup Open Graph image -->

{% if page.image %}
  {% assign src = page.image.path | default: page.image %}

  {% unless src contains '://' %}
    {%- capture img_url -%}
      {{ src | absolute_url }}
    {%- endcapture -%}

    {%- capture og_image -%}
      <meta property="og:image" content="{{ img_url }}" />
      <meta name="twitter:image" content="{{ img_url }}" />
    {%- endcapture -%}

    {% assign old_meta_clip = '<meta name="twitter:card"' %}
    {% assign new_meta_clip = og_image | append: old_meta_clip %}
    {% assign seo_tags = seo_tags | replace: old_meta_clip, new_meta_clip %}
  {% endunless %}

{% elsif site.social_preview_image %}
  {%- capture img_url -%}
    {{ site.social_preview_image | absolute_url }}
  {%- endcapture -%}

  {%- capture og_image -%}
    <meta property="og:image" content="{{ img_url }}" />
    <meta name="twitter:image" content="{{ img_url }}" />
  {%- endcapture -%}

  {% assign old_meta_clip = '<meta name="twitter:card"' %}
  {% assign new_meta_clip = og_image | append: old_meta_clip %}
  {% assign seo_tags = seo_tags | replace: old_meta_clip, new_meta_clip %}
{% endif %}    

{{ seo_tags }}

Thank you @bigsk1. I can confirm after using the local template with these changes, it works timothystewart6/techno-tim.github.io@4608f15

[timothystewart6]

hmmm, this seems to have broken it on other platforms (discord)

[bigsk1]

try removing

<meta name="twitter:card" content="summary"> 

from top of head ?

[bigsk1]

testing open graph shows ok

[timothystewart6]

interesting. It does look correct on OG however it does not in Discord

I am not too familiar with liquid but it seem like there's a page image getting assigned and a site image.

[timothystewart6]

I see, now I have 2 og:image tags. Trying to fix

[timothystewart6]

All fixed! Seems like it is now fixed for both twitter and og cards. I have an image preview in twitter and the images on other socials only render once: https://github.com/techno-tim/techno-tim.github.io/blob/master/_includes/head.html

I am happy to open a PR, but @bigsk1 did most of the work and I am not sure if my hacks to his liquid code are right 🤣

[bigsk1]

oh nice I was off trying to solve also and saw this great, let me check it out

[timothystewart6]

Proof that it worked on twitter:

Proof that it worked with OG
https://mastodon.social/@technotim/111785120941155450

I actually posted this on all socials (FB, LinkedIn, etc) and it rendered fine everywhere
