DESCRIPTION

sigplus adds photo and multimedia galleries to a Joomla article with
a simple syntax. It takes a matter of minutes to set up but comes with
a vast range of options for more advanced users.

Even while simple to use, sigplus offers an impressive set of features.
Images suitable for gallery preview are automatically generated with
cropping and/or centering, and clicking on a preview image brings up a
pop-up window overlay (so-called lightbox) showing the original image
without navigating away from the current page. Images in a gallery can be
displayed in fixed or flow layout, they can be shown on a slider/rotator.
Appearance and behavior are highly configurable including image margin,
border, padding, slider/rotator orientation (horizontal or vertical),
animation speed, slideshow delay, image sort order, etc.

Despite its versatility, sigplus is completely free. It is a full-fledged
product with all features included, there is no need to buy a commercial
professional version for extra features or purchase club membership to
unlock additional privileges. Since its publication in the Joomla
Extensions Directory in March 2010, sigplus has been rated the best
extension in the "Photo gallery" category.
