I have already sent a bug report to Opera's team.
BTW, regarding your comment that you have no problems viewing that webpage, I forgot to mention that only the first image is displayed, and all other images are not displayed.
Numbers will be displayed below "where each image is supposed to be" in the article.
In case you have the opera mini ad blocker enabled, you will notice that 16 "ads" have been blocked for that web page. They are actually false positives (genuine images incorrectly identified as ads and blocked).
One month ago, I could disable the Opera Mini ad blocker to display all the images below the first image, but
now it does not make any difference. Images are still not displayed.
Originally, Opera Mini was able to display all the images without any hitches some months ago.
All other images below that article have blank spaces.
