AIMG Strengths

  • Provides a robust, tamper-evident cryptographic wrapper to definitively prove the origin of AI-generated media
  • Header-first structure allows verifier nodes and APIs to validate an image's origin without needing to download or decode the entire massive pixel payload
Limitations
  • Lacks native rendering support in browsers, requiring server-side extraction or client-side WebAssembly to display the embedded image
  • Utilizes the IANA 'prs.' (personal/vanity) tree rather than the standards tree, which can cause strict enterprise firewalls to reject the MIME type as unverified
SLD

SLD Strengths

  • Allowed for instantaneous loading of highly complex architectural and engineering blueprints on low-memory MS-DOS systems
  • Easy-to-parse binary structure containing simple opcodes for drawing vectors and polygons
Limitations
  • Completely obsolete and heavily fragmented, largely replaced by PDF and lightweight web-based DXF viewers
  • Destructive 'snapshot' format irrevocably strips all useful, editable CAD geometry data from the original drawing
  • Zero support in web browsers or standard image processing libraries
