Look at all the features!
Show/Hide Gallery Controls
Multiple Transitions (including random)
Is easy to customize and suits very well to se it as a simple slideshow or a good way to make something diffeent to our site's background.
Like we say here is money well spent.
It is very intuitive even for the most inexperienced joomla user.
I guess, Pros & Cons may vary on each personal application... so, the following are my own experiences and needs.
You can assign the Plugin to certain MenuItems. It seems to offer all current SuperSized features.
Because it is a plugin, you can't use multiple instances. Therefor, you can only use it with one configuration! i.e. 1 image source folder. Or 1 flickr gallery. A module solution would be more versatile, because you could use different folders and different modes!
Currently no PNG overlay as default or optional parameter.
If you just need one instance, or you see another technical benefit in the plugin architecture, than buy it. I have to admit, that the support is kind and listening. More features might be included in the future.
If you need multiple and different display modes on one site, you might checkout a module-based version.
If you want to try SuperSized, without paying a buck, than lookout for a free version in this extension category ;-)
We listened to our customers needs, including this one and we now offer this extension as a module as of July 2012. It just made more sense. Now you can have multiple galleries on your site. There are free solutions, but we offer full support and free upgrades for a year.
