Topic: 'Home' button help for someone with absolutely no idea. Help

I've just finished building my photography website using iweb and Lightroom. I've created a main menu page for my site and used the brilliant Autoviewer software within Lightroom for my photo gallery slideshows.

The people I've shown the site to have one suggestion which is to have a HOME button within the slideshow that will take them back to the main menu.

Here's the thing, I've looked through this forum and have no doubt found the answer. Problem is, I have absolutely NO idea what you guys are talking about. I have zero HTML experience.

So my question is this, and any help would be very appreciated. Can someone tell me, in layman's terms, how I would add a HOME or MENU button to my slideshows.

You guys have the knowledge. Please throw me a bone here! :)
