The Gallery widget places an image gallery on your page. There are three options to choose from (shown below). With the default and mosaic views, when an image is clicked, an overlay screen launches with the rest of the images for easy viewing. Mosaic view will resize the images to fit them together differently and upon refresh will shuffle them in a new way.
It is not necessary to crop images consistently. We do recommend downsizing the photo resolution or run the images through an image compressor/optimizer before loading. This helps the page load quicker.
