A guide to creating vacation-themed web banners and techniques for changing image aspect ratios from square to 16:9 using revision prompts.
Default Image Size Tip
By default, ChatGPT often generates images in a square format. If you need a website banner, always specify '16:9 aspect ratio' in your initial prompt to avoid extra steps.
Detailed Revision Feature
Every time you click on a generated image, you can use the revision feature not just to change the size, but also to 'remove' or 'replace' specific elements within the image using simple text instructions.
