It happens only on Flickr, but this is the only place I find this sort of image layout. Basically, there is a 2x3 grid of place-holders for images. But in Opera, the place-holders are displayed in one long string of six, not in a 2x3 grid. The string of six place-holders overlays other content on the page, rendering it inactive.
It is as if it is not interpreting the page's script correctly, but I don't have the expertise to isolate what is going wrong.
