OpenLayersZoom in Big Picture

I’d like to use the Big Picture theme together with OpenLayersZoom to replace the static “big picture” of an item’s attached file with a “zoomable” picture of the attached file. (For this project I have just one image per item.) In my current configuration, with OpenLayersZoom installed as a plugin, I have ended up with a large “big picture” taking up the left two-thirds of my item page and a small “zoomable” image wedged below my item metadata in the right third. How can I adjust the theme files to implement what I’d like to see?

Can you show a screenshot of what’s happening?

Probably the issue is that the fire_plugin_hook call on your items/show.php view is inside a sidebar of the theme; just moving that call into the main container would be an option.
