Use an image that you have the right to use, such as one you own or have permission to upload. Ensure the image is in focus, well-lit, and high resolution to achieve the best results. Choose an image with a clean, uncluttered background, clear edges, and minimal obstructions. Avoid images with heavy shadows, blurry details, or low-quality resolutions, as these may affect the output quality.
You can also draw your idea, sketch it out on paper, take a photo, and upload it.
