Gallery+ provides four different gallery types
This is the original Gallery+ style, laid out with a main image and thumbnail strip and is useful from small to large numbers of images.
The Accordion style shows the images in sliding panels with vertical titles. It is useful for a small number of images and, with the ability to link to a URL, be useful as an entry to other galleries or pages
Provding a 360 degree rotating carousel of images, the carousel is a nice way to show off a smallish number of images
When all you want is a grid or linear display of images, the ThumbGrid layout meets that need. It has one feature that none of the other gallery styles have though – the option to "zoom inside", that is, show the larger dispaly image floating within the thumb image when the user hovers over it.
