Image Manipulation for Amazon SiteStripe is a simple WordPress plugin that can be used to make some minor manipulation for images sourced from Amazon SiteStripe. It was originally developed to make working with the Amazon Associates SiteStripe images a bit easier as they easy to manipulate once the HTML is added to your site.
It simply centres the image and scales it up a bit, as the image size provided by Amazon are small. It also adds a CTA button to help improve conversion rates. The colour of button and size of image are able to be changed on the plugin settings page..
You can find the plugin in the WordPress plug-in directory here, to download and add it to your WordPress site.
