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 full-size 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 or carousel/rotator, or an image can blend into another using a fancy transition effect. 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 with extra features or purchase club membership that grants you additional privileges.
Translations included: English, Dutch, French, German, Hebrew*, Hungarian, Polish, Portuguese, Russian, Slovak and Spanish* (asterisk indicates front-end only). Joomla 1.5 users should install plg_sigplus-1.3.x (and optionally mod_sigplus-1.3.x), users of Joomla 2.5 and later should use the package installer pkg_sigplus-1.4.x (click "Download" for the latest version released in the series to date for maximum compatibility).
Only "downside" is that editors of items will have to deal with shortcode; simple enough though.
What I am missing a little are the SigPlus extenions like search and the editor buton for Joomla 2.5. I've tried one that I found, but it didn't work. Despite that, the extension is brilliant and surprisely free.
Thank you so much for this woderful extension.

On the other Joomla 2.5.4 working correctly
If the installation of sigplus succeeds on one Joomla system but fails on another, I would suspect a problem with the operating environment (e.g. folders that should normally allow write access lack write permission) rather than a sigplus-specific issue. In any case, it is best to contact the developer directly with problems related to the extension; the Joomla review system is most unsuitable for seeking help. In particular, your e-mail is not revealed that would allow writing a response.
