From Myriad Software:
Galerie exports the current iPhoto selection to Web pages. You can also generate a gallery from a set of pictures files not present in iPhoto. For each selected picture you will get a separate HTML page that enables to navigate to next and previous page. An index page, called 'Index.html' is created and shows all the pictures as icons. You do not need to know the HTML language to use Galerie. Version 3.4: HTML tags can be included in comments and other text fields. Option to quickly regenerate HTML pages for the last generated gallery when no changes to the images are needed. You can now define the opacity of the imprinted text background. Now in both vertical and horizontal frames thumbnails are synchronized with browsed pictures.
