The client was using our Gallery plugin for sometime and liked it very much. He upgraded to pro hoping to get a few more features to make the site more dynamic, but it turned out to be not so sophisticated as he had hoped. So he contacted our support team with a request for customization. The client wanted his viewers to be able to scroll through each picture and if they decide to purchase an item have a purchase button (link) that takes them to his offsite transaction. Also it was necessary to make it possible to add description to the purchase item. The work was completed within a few business days and now these features are available in the Pro version of the plugin.
