I've just finished the product reviews section of StoreSuite. You fill out the product review form as usual, however to prevent spam you have the option of using a CAPTCHA image on the review form. If your server has PHP's GD library then a gradient image will be generated like so:



If not, then multiple images will be used to display the CAPTCHA sequence, like so:



95% of the CAPTCHA class we use to prevent comment spam in StoreSuite comes from ArticleLive, so thanks to Jordie for the class! To check if the server has GD support, we simply run the GDEnabledPNG() function, which looks like this:

/**
* GDEnabledPNG
* Function to detect if the GD function for creating PNG images is enabled.
*
* @return Boolean
*/
function GDEnabledPNG(){
    if (function_exists('imageCreateFromPNG')){
        return true;
    }
    return false;
}

CAPTCHA is the most popular way to prevent automated spam submission robots using forms on your site to submit spam. Speaking of CAPTCHA, here's the product review form:



Reviews can be approved automatically, which means they will show up as soon as they're posted - much like comments on a blog. If not, each review can be manually reviewed and approved through the StoreSuite control panel.

Finally, I just wanted to emphasize that all links in StoreSuite are "shareable". For example, if you use the comparison wizard to compare products, the link might look like this:

http://www.yourshop.com/compare/1146/1151/1145/1153/1144

The link is easy to share with friends, just like all other product, category, search and page links in StoreSuite. Nothing's more frustrating than trying to share a page on a site with someone else only for them to be presented with a session timeout message when they try to view the page (this happens on seek.com.au and it frustrates a lot of my friends looking for jobs).
