@Admin First Problem: Some of my site’s image don’t show. It don’t display high resolution pictures but it can display low resolution pictures.
**Second Problem:**I only registration one domain. When I put www in my url I see maximum image is displayed rarely some of picture not displayed. But without www I don’t see maximum pictures.
Response for First Problem: For me some site images show correctly with high resolution images, but it may be a favor if you optimize them using ShortPixel compression tool and the Lossy mode on it.
Response for Second Problem: You can register as many domains as you want if they’re available from Freenom. For me some images work from both www and non-www versions. Maybe try removing cache and cookies or use 1.1.1.1. And correct URLs of the images, because on Linux systems the name of files uploaded are case-sensitive, so correct them with the correct versions.
On the location image/ocation/ the images names are all in small characters (example: olympiad (1).jpg). On the HTML files, change the name of the images with the correct ones. Check the image/ folder for yourself and see if there are any changes to do. If yes, then use the Online File Manager, edit the HTML files with the broken links and remember to save the changes after editing.
