Those are site suggestions and, as you can see, the only images are the sites logos. They are generated based on your browsing history.
There may be promoted suggestions eventually but they will look exactly like those on the image. And if you click on them, the site main page will be opened.
Those are the only suggestions that Opera shows, except for the search ones but those don't have images.
If your problem is with those suggestions, you already know what to do and there is nothing more to be discussed here.
If your problem is with something else, then you will have to better explain it, with education and good manners, following the instructions.
