Confirm this is a feature request for the Node library and not the underlying OpenAI API.

• This is a feature request for the Node library

Describe the feature or improvement you're requesting

I'm experimenting with gpt-image-1.5 via a Microsoft Foundry playground, within that I have the option to supply a single reference image along with a text prompt
e.g. a photo of a person
and a text prompt "show the person running through a field of wheat"
I assume the underlying API has the functionality as foundry is able to generate something, but I cannot find the functionality to achieve the same thing within this module
Apologies if this is already something that is possible

Additional context

This is an example of my generate call, image is not currently a supported parameter, and that is the kind of thing I'd like to include, supplying a base64 string

            const result = await openai.images.generate({
                model: "gpt-image-1.5" //I've also tried with gpt-image-2
                image: <base64 string>,
                prompt: <prompt text goes here>,
                n: 1,
                size: "1024x1024",
                quality: "low",
                output_format: 'png'
            })
