In InstantPro there are two types of gallery you can create.
Static Gallery: You can use this to display Thumbnails of all of your images, which will display full size images when clicked.
Slideshow Gallery: This will automatically flick through the images you upload and display captions.
Once you've decided which type of gallery you want, take a look at the tutorials below to get started.
