When an article is published on your blog, it arrives as blog content in Plezi (thanks to the RSS feed). Once in the content, you can edit its title, description, score and tags.
The image, on the other hand, is directly linked to the one in your blog post when you import it into Plezi. If you update the image in your article AFTER you have published it, you can request to synchronise the image in Plezi by clicking here :
This will update the image in Plezi. 🎉
The new image will then be presented to you :
in the content tab
in the tool for promoting the article on social networks
in the automated newsletter.
