Missing images when sharing links
There are a lot of reasons why an URL cannot be properly shared on social media platforms like Facebook, WhatsApp, etc. Most of the time, an invalid image is shown or the image is completely missing. To determine the cause of this, you can use Facebook Debugger tool.
In general, make sure your image URLs contains only alphanumeric characters, dashes or underscores otherwise Facebook will reject them. You will have to rename all your image folders and image names and remove bad characters like spaces.
