New Tutorial: Managing User-Generated Images

• Published another in our series of tutorials, this time about using imgix to standardize user-generated content for a better user experience. Bonus experimental section on using images as their own masks for product photos.

Base64 Variant Parameters

• All values passed to parameters in the imgix URL API can now be encoded using a URL-safe Base64 scheme. To enable this encoding, simply append 64 to the end of a parameter name (e.g., txt becomes txt64). More details can be found in the imgix documentation.
