This is a demo gallery which you can delete at any time.
You can add a description to each gallery (like this) and format the text as required.
This thumbnail display uses the masonry style which auto-arranges multi-format images into a neat grid. You can also switch the gallery to standard fixed grid format (as illustrated in the Private Gallery). You can also make the thumbnails square using the auto-crop feature when you upload them into the galleries (as demonstrated in the second demo gallery).
