Some images not showing on Safari

Hi,

On my website (https://www.moriczdental.hu | WordPress 5.0.3 ) the PNG and some of the JPG images are not showing in SAFARI.

If i try to open only an image frome the server it gives an error:

“The file “logo.png” could not be opened.

It may be damaged or use a file format that Preview doesn’t recognize”

Also some of the .jpg files are not working.

Any help would be much appreciated.
