Generating image thumbnails

Large images can be a difficult issue for website. They increase the size of the web page and make them slower as a result. This leads to bad SEO rankings and visitor abandonment. In this recipe, we will explore how you can create images of different sizes.

image = fields.Binary(attachment=True) # 1024x1024px
image_medium = fields.Binary(attachment...
