Optimized image delivery has been around for a long time and one open source technology that has provided this to thousands of sites in WordPress is ImageMagick. I have been a huge fan of ImageMagick because it’s so darn simple and straightforward.
Trilibis, a certified IBM Commerce partner has a WebSphere Commerce extension (SNOW IO) that brings image optimization delivery to this extensible platform. The way it works is you install the ImageMagick software on your server and configure it to point to where your images are stored on the server. You then configure a job to run frequently (hourly, daily, weekly) to resize images stored in that directory. The default setup will create three versions of your images – Desktop, Tablet, and Phone sized images.
Check out my video below where I show how I configured SNOW IO to work with the out of the box Aurora starter store in WebSphere Commerce.
