## What
Since `langchain_google_genai.ChatGoogleGenerativeAI` supported A public
image URL, we add to support it in `langchain.chat_models.ChatVertexAI`
as well.
### Example
```py
from langchain.chat_models.vertexai import ChatVertexAI
from langchain_core.messages import HumanMessage
llm = ChatVertexAI(model_name="gemini-pro-vision")
image_message = {
"type": "image_url",
"image_url": {
"url": "https://python.langchain.com/assets/images/cell-18-output-1-0c7fb8b94ff032d51bfe1880d8370104.png",
},
}
text_message = {
"type": "text",
"text": "What is shown in this image?",
}
message = HumanMessage(content=[text_message, image_message])
output = llm([message])
print(output.content)
```
