I want my homepage slideshow to be the first thing visitor see. I want it to stretch the full width of the page. How do I do that?
In order for the slideshow to be the first thing the visitor sees, you need to make sure the slideshow is at the top. If you are using the built-in Smugmug slideshow, be sure to select 'Slideshow' in the 'Homepage Layout' button on your Homepage, and select 'move up' from the 'Organize' selection at the top of each section.
However, the built-in slideshow will not allow full width stretch. If you want stretchy photos, you need one of the custom slide shows. This also means a bit of customization, as you will need to embed the show in the 'Bio' box, and therefore should ensure that it is the item at the top of the screen (be sure to uncheck 'Slideshow')
If you really want full screen, like every inch of available screen stretch, you should check out the FastLine Media Full Screen slide show customization
Here are samples to show you the options:
