Since the beginning of Joomla I have been using all kinds of components to create a gallery: Ozio, Phoca, Joom, etc...

The functionalities of a gallery are very obvious: thumbnail, description, view categories, additional info fields, etc... and ooops, i saw a great similarity, Joomla doesn't need a gallery component, all those features are already there: category view, a main image, short and extended description (read more), custom fields.

There are only two things the article component needs to be perfect gallery:
1 ) article full screen view
2) and next and back buttons that transition from one article to another.
This would be enough to create galleries, presentations, slides, product catalogs, photo albums, newspapers, digital magazines.
All the code of the Category Blog view could be duplicated and only two new ones are added.

By assigning a menu button to the component we would have this wonderful option:

The view would be like the blog format (we could choose columns, categories, etc...) the introduction of the articles would be shown, but the title or linkable image of each article would execute the article in full screen view.
