Need image dimensions from S3 or a CDN?

by Giménez Silva Germán Alberto —

Need image dimensions from S3 or a CDN? Don’t download the whole file. FastImage reads the header—1-16KB instead of megabytes. 5-199x faster. https://rubystacknews.com/2026/03/20/fastimage-overview/

Pure Ruby. Zero dependencies. Done. #OpenSource #DeveloperTools #TechTools #ImageProcessing #CDN #S3 #AWS #Ruby
