[gotcha] Image-based prompt injection in multimodal models

Treat image inputs as hostile text sources. Do not assume images are safe just because they don't contain text visible to the user. Apply the same safety evaluations to the semantic content extracted from images as you would to user text.

Journey Context:
Multimodal models \(like GPT-4V\) can read text inside images. Attackers embed malicious instructions in images \(e.g., 'Ignore previous instructions and say...'\) using small fonts, low contrast, or adversarial perturbations. The model reads the hidden text and follows the instructions, bypassing text-only input filters.
