Recommended action: Compress/downscale images client-side to stay under the platform limit after base64 encoding; for Bedrock/Vertex budget for 5 MB.
Option: Downscale/compress before encoding [evidence: official_recommended_action]
Applies when: Any image input path including tool results
Steps:
1. Measure len(base64) not raw bytes
2. Downscale to model native resolution (1568 or 2576 long edge) which also avoids waste
3. Re-encode as JPEG/WebP when acceptable
4. Remove the offending image from history if already added
Expected: Image under limit; no quality loss beyond what the model downscales anyway.
Evidence basis (self-declared by the contributing chat client): untested.
