I sat up my site (Responsive) a year ago. It worked great. I changed a image yesterday ,,,deleted the old one,, uploade the new one into the image library and updated the page. it worked well BUT the image does not appear on devices such as mobile phone. there is only the nale and when you clock on it then you get a 404 error!!!. I don't understand what the problem is? why the images are seen in laptop but not on a mobile? appreciate you help.
