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).

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.
If I use multiple time this component in the same page and at different module position, happens this:
The highest slideshow in the module positions works perfectly, the following ones loose the resolution of the image after few seconds.
I am afraid this problem is not related to sigplus in any way. Instead, it appears that some third-party extension is interfering with sigplus, and causes it to malfunction. If I were you, I would take a look at my smart image loader extension or my template if it ships with a built-in smart loader. Unfortunately, sigplus cannot be prepared to counteract aggressive extensions that either intentionally or unintentionally refuse to be nice and play by the rules.
Clicking the "Download" button will take you to the JoomlaCode "Browse releases" page where you can obtain all sigplus releases. Basically, there is a version for Joomla 1.5 (sigplus 1.3.x) and a version for all other major Joomla releases. In particular, sigplus 1.4.x (in the package "Joomla16-Joomla25") is what you are after, which covers all Joomla versions 1.6 and up (including 2.5).
We have found that it can sometimes display incorrectly on iPads, despite showing up fine in the Safari browser when accessed from macs/laptops. Curious to know if the developers are aware, or if this something that is a freak issue for us.
Again though, incredible app.
