When viewing the gallery macro from opera browsers the picture is rendered at the bottom of the whole page not over the current view.

To reproduce the problem:
Start Opera 9.50 (doubt that version matters)
Open http://wikis.sun.com/display/gridengine62u2/Express+Installation page
Click on series of 4 pictures (gallery macro)
=> You don't get the picture just the black effect. Picture is actually
rendered, but after the end of screen. One has to scroll down to the end of the
document!
