I run an instance that caters to various Free Software photography projects. I’ve created specific categories for each project to use as their own.
I am thinking it might be nice, from a social outreach perspective, to allow them to specify metadata images for each individual category.
For instance, the RawTherapee project has a category here: discuss.pixls.us - Free Software Photography
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”?
