I've finally figured out that using the "font-resizer" jquery plugin in conjunction with the "wp-content-slide" plugin causes the content slide to make the photos one on top of the other (no jquery functioning there I think). The strange thing is that is works fine on my local machine, though on my local machine they were probably installed in a different order before 3.1 was released. Both are now running 3.1 though.
Please help! I'd love to have these two plugins working together!
