This plugin makes a grid of thumbnails on the right and displays each picture in large size on the left.
I use Elegantwhite as theme.
As plugins, I use only Quick Cache and Photo Galleria
It seems to happen only on my site:
everytime I move the mouse over another thumbnail, the large picture area "disappears" and the grid which was on the right gets to the left.
Any idea why it would be doing that?
