So here's my question. How can I prevent this from happening? For example, I have created a website for a client. It has her picture in front of a filled-in shape. When I update her site, the picture turns into a grey square. But if I click refresh, the site looks fine.
This issue is only going to happen to people who have visited the site prior to the update, but I want to ensure that all visitors see a clean, accurate website. Again, how can I prevent this from happening?
Thanks!
