Thanks for the quik reply. This is definitely an issue as it never use to do this before. If you browse 4-5 pages on the site on your mobile device, scrolling up and down on each page, you’ll see images disappear after loading or not even load at all.
Good examples are reviews where the Related Article images do not load, whereas they use to.
This problem has been happening since I updated the theme with all the plugins the theme requires switched on.
