Labels: 🤖:bug

### Checked other resources

- [x] I added a very descriptive title to this issue.
- [x] I searched the LangChain documentation with the integrated search.
- [x] I used the GitHub search to find a similar question and didn't find it.
- [x] I am sure that this is a bug in LangChain rather than my code.
- [x] The bug is not resolved by updating to the latest stable version of LangChain (or the specific integration package).

### Example Code

Not able to get the images for the webpages return by tavily results. 
Like [end of cold war](https://coldwar.unc.edu/theme/end-of-the-cold-war/) this page has images but i did not recieve it.
This is inspite keeping include_images=True in parameters.

Environment : Google colab

### Following is the minimal reproducible code 
```python

%pip install -qU "langchain-community>=0.2.11" tavily-python


import getpass
import os

if not os.environ.get("TAVILY_API_KEY"):
    os.environ["TAVILY_API_KEY"] = getpass.getpass("Tavily API key:\n")

from langchain_community.tools import TavilySearchResults

tool = TavilySearchResults(
    max_results=5,
    search_depth="advanced",
    include_answer=True,
    include_raw_content=True,
    include_images=True,
)


tool_results = tool.invoke({"query": "What happened at end of cold war?"})

tool_results

```



### Error Message and Stack Trace (if applicable)

_No response_

### Description

- I am trying to use langchain integration with  tavily seach using from langchain_community.tools import TavilySearchResults
