http://www.imcdb.org/vehicle.php?id=475616 was one of the examples of what I called your thumbs above - particularly because I wanted to see the fake castle, so it was something happening before and beyond "pics.imcdb.org", but only on your thumbs as far as I can tell and only started recently (last month or two). Could just as easily be something in the Opera settings as installed on my laptop instead of a wider issue, but I can't see an obvious way of checking/changing my settings, and am unsure/cautious about exploring technical stuff within scary-looking headings.
