 The `images` parameter accepts a sequence of raw `bytes` (e.g., PNG/JPEG data) or `gl.nondet.Image` objects.
 
+## Passing User-Supplied Images
+
+Raw image bytes are convenient for small test fixtures and controlled inputs, but avoid pushing large image files directly through transaction calldata. Large payloads are harder to submit, review, and reproduce across environments. Prefer passing a stable external reference that validators can independently fetch.
+
+A common pattern is:
+
+1. Upload the image to a public HTTPS URL or a content-addressed location such as IPFS.
+2. Pass the URL, and optionally a content hash, to the contract.
+3. Fetch or render the URL inside the non-deterministic block.
+4. Send the fetched image or screenshot to `gl.nondet.exec_prompt(images=[...])`.
