Any suggestions why only some of the images have re-appeared and what else I need to do?

Thanks in advance!

a) Homepage – https://www.growyourbusinesssuccessfully.net – image missing on static banner(lower half of the page)

b) About page – https://www.growyourbusinesssuccessfully.net/about-business-growth-coach/ – 3 images missing in the middle of the page

c) Show page – https://www.growyourbusinesssuccessfully.net/about-business-growth-coach/ – image missing on fixed banner
