GitHub has expanded its image proxying strategy by including HTTPS images in addition to non-HTTPS images, using a custom node server called camo, to enhance user privacy and improve performance. This change ensures that browser information is not disclosed to third-party services, thereby protecting user privacy. By routing images through a CDN, users can expect faster load times and fewer instances of broken images on the platform. This update is part of a broader effort to enhance security and performance across GitHub, as highlighted by related open-source updates like camo SSL proxying and changes to html-pipeline.
