To execute an action when the page loads you need to reach for a Head
Action Item which is located in the Smart Objects tab of the Objects
palette; it's identified by a little question mark. There's another
one that looks very similar - the Body Action Item - so watch the tool
tip at the palette bottom to make sure you grab the right one.

Drop that anywhere onto the page - GL should place it automatically
in the head section of the page which also pops open at that point.

Now you need a base image on your page and name it in the "More" tab of the Inspector palette. Next you select the Head Action Item, assign the SlideShowAuto Action to it and select your base image in the Inspector. Usually your base image is the first slide in the sequence.

That's all there is to it.

By the way, your question isn't really related to dynamic content which is a technology for building database-driven websites - you'd get more help if you'd post such questions in the general GL user forum :-)
