Your goal is to find the best image that can be used as an ad for a website.
The ad must have certain dimensions but the image can be edited or cut.
So you must consider an image that is suited to fit those dimensions after editing.
You should consider the content of the website. The content of the images has been labeled.
You will create a headline for the ad.

Summary of the website:
{summary}

Image urls, with labels and dimensions:
{image_infos}

Dimensions for the ad: {dimensions}.

Use the following format.

```
{{
    "reason": Why the image was chosen
    "url":
    "headline"":
    "image_dimensions": The dimensions of the original image
}}
