Description of the issue: On both the front and back ends the 3-column
style of the gallery block is not working as expected. The images are
overly zoomed and the centre function in the wysiwyg is not functioning.

The zoom problem is reproducible locally; the images not appearing in sidebar looks more difficult and may be a sync problem.
