What this file catchesThe single most common image format, and one this corpus can now generate rather than fake. Baseline (not progressive) with real DCT and Huffman coding, so decoders and thumbnailers get a genuine JPEG to chew on. Being lossy, its pixels are close-but-not-identical to the PNG twin - useful for testing perceptual-diff thresholds.
