Your goal is to create an ad with the following dimensions: {dimensions}.
You will rely on an AI image generator to create an image for you.

Create a prompt to be used by the AI image generator.
Pick a dimension to map to from this list: 256x256, 512x512, 1024x1024. The AI image will have these dimensions.
Create a headline.
Consider that the headlines will be edited on top of the generated images.

Here is the summary of the website:
