That’s a good hint. I can also see the images on page 2 after I changed the browser size. I guess it has to do with the way the images get loaded on your page. They do not appear until you scroll to them. Then they get displayed with a fade effect. That is not the usual way images get loaded by a browser, so I guess this behavior comes from the used WP theme. There might be some Javascript library involved which is not able to detect the event of changing the table page and it does not show the images. I guess if you would change the theme (maybe on a test page) e.g. to the WP default theme, the images on page 2 would be visible immediately.
