I occasionally post to twitter/facebook/google+ about posts from that category. Right now, the social platform picks up the default opengraph image url and twitter summary large image url values and shows the images correctly. But they’re site-wide.
I know that the projects would love to be able to control this branding themselves possibly. Perhaps as another image option on the category settings? Maybe as a “Category Metadata Image”?
Wanted to lift up this topic. Often the image for the category is a specific size that suits the top of the category. However, I’d like to propose that the category og:image could take the og:image associated with the About the category topic.
Hi,
Can someone correct me if i m missing anything that needs to be done for this task.
From what I can gather
Add a new category similar to logo and background image for meta.
Store image for this new category.
What else needs to be done with that image after it is uploaded and saved for this task? Does it need to be shown somewhere and/or add some specific meta data?
For now, was just thinking the category link. That will go far. I don’t think we want to get into impacting behavior on topics from the category, though it’s not a bad idea. Perhaps it could be a checkbox option, and would be used if no other image is available. Certainly for backlog, not for now.
This is how sharing a category currently looks. Would be nice to also be able to overwrite the og:title, so instead of just Thalia for example, it could say something like “What’s the community saying about Thalía?”
These changes could really help us grow our community
For a future request, I’d love to see how admins could specify promotional metadata for a topic that would not be editable by the end user. But I’ll create a separate topic for that once we see the value of this change on the categories
I love seeing the questions, and the activity around this.
I would agree that this would be nice for the base category link. So in my instance, I’d like to see the custom logo for direct links to a category like this:
I would imagine that if a topic doesn’t have an image in the first post to pickup for linking, then use this as well?
So this topic in that category has an image in the first post, and uses it:
This other topic in the same category doesn’t have an image in the first post, so uses the default site-wide logo (this is the one that should also use the custom logo):
I think there’s merit to that, but I imagine it requires much extra work and we should really get out the category link image. And if we are going to allow inheriting the image on the topics, this should probably be a setting at a community level, and perhaps a category level
I was reviewing the PR and feel that uploaded_sharing_id is really confusing. Perhaps we can make it more inline with the naming we used for site settings like SiteSetting.opengraph_image? I would prefer something like Category#opengraph_upload_id.
Also if I could turn back time, I would have named uploaded_logo_id and uploaded_background_id as logo_upload_id and background_upload_id respectively.
otherwise I can take a look once I start progressing on my backlog
