This is neat and could apply to some of the use cases we've implemented at Product Hunt (e.g. social cards for user profiles, email newsletters highlighting the latest launches, etc.).
What started as a quick way to generate images for social sharing blog posts using HTML and CSS; turned into a way to generate personalized images in an email on the fly when opened or build my own version of that image you embed that shows where all your visitors are from around the globe. The ability to quickly do this HTML and CSS without needing ImageMagick gave birth to OpenGraphImage.com.
What are some of the other ways you’ve seen personalized images generated at scale?
