This step requires you to sign in to your Google account and, if it's your first time using ImageFX, you'll need to click through the AI Test Kitchen's email settings, such as whether or not you'd like to receive marketing emails or research invitations. You'll also have to review the AI Test Kitchen's privacy policy and terms of service.

Google will also give you a brief overview of ImageFX, explaining what it is, reminders to respect the rights of others, and explaining how AI-generated images can include mistakes. 

It's important to be as detailed as possible when you enter a prompt for image creation. Try to imagine the image you want to see and then write a description of what you want. 

It's worth adding the format of the image you want, such as whether it's a photo, a 3D render, a drawing, etc. You can go as far as adding a style, like impressionism, abstract, vaporwave, etc.

I'm using the prompt, "photo of a kangaroo in a colorful bakery looking at desserts in a display case with flowers and pastel colors."

ImageFX lets you view the four images it created with your prompt, and you can click on each one to copy the prompt or the image, download them, and share them.
