🚀 Feature: Upload Langchain input images to storage

[dinmukhamedm]

Which component is this feature for?

Langchain Instrumentation

🔖 Feature description

Allow uploading base64-encoded image inputs to LangChain models to storage, similar to what was done for Anthropic in #2029

🎤 Why is this feature needed ?

Basically, because LangChain allows both url and base64 inputs (similar to Anthropic), though they call either payload type image_url🤦‍♂️

See: https://python.langchain.com/docs/how_to/multimodal_inputs/

✌️ How do you aim to achieve this?

Similar to #2029
