[BUG]Incorrect description of the images parameter in MultiStepAgent.run

[iejzh]

Description:

The documentation for the images parameter in MultiStepAgent.run is inaccurate. The current docstring states that images accepts paths to images (list[str]), but in reality, the implementation does not support image file paths or URLs. Instead, it seems to require a different type of image input, such as preloaded image objects (e.g., PIL images, NumPy arrays, or Base64-encoded images).

Current Docstring:

images (`list[str]`, *optional*): Paths to image(s).

Issue:

• The method does not handle image file paths or URLs.
• If passed a file path, an error occurs because there is no internal loading mechanism.
• Users may be misled into thinking they can provide image paths, causing unexpected failures.

@aymeric-roucher should we change the code and docstring like

images: Optional[List[Any]] = None,
"""
images (`list[Any]`, *optional*): List of image to process.
"""

or we need to change code to handle image paths.

Thanks for reporting, @keetrap.

I think current implementation only supports PIL.Image.Image objects.

@albertvillanova Should I raise a PR?
