Hi, thanks for trying Meteor Slides. If you are using the Weaver theme, you don’t need to edit the theme’s code, you can make these changes through the theme options.
From the documentation for the latest version:
For example, assume you’ve installed the Meteor Slides plugin, and have uploaded your rotating header images for the plugin to use. To add this slide show header image, you should first disable the default header image by setting the header image size to zero in the Main Options tab. Then, add this code to the Site Header Insert Code box:
<div class="ttw-center">[meteor_slideshow]</div>
Note that the built-in ttw-center CSS class will ensure the slide show is displayed properly. Without appropriate CSS styling, you may get unexpected placement of the plugin output. The ttw-center class will usually do what you want.
