Banner image not updating

When I change a banner image, it looks fine in Preview and Print to Safari but the old one remains on the published and refreshed page.
I’ve republished all files and marked all pages as changed.
I have to delete the old banner and create a new one with the new image.
It’s been an ongoing thing for me but as it’s just happened again, I thought it’s time to ask the forum.
Thanks

Hi Philippe,

Sorry about not replying to either post. To be honest, I didn’t see them in my inbox, and I must have forgotten about my original question. In any case, there doesn’t seem to be a problem any more.
Appreciate your interest.
