OpenAI DALL-E Image Generation API

The OpenAI DALL-E API generates images from text descriptions, enabling businesses to create product visuals, promotional banners, and marketing assets programmatically. ShopMax India uses the DALL-E API to auto-generate product category banners for its website and create personalised promotional images for seasonal sale campaigns across Mumbai, Bangalore, and Delhi storefronts.

Image generation uses client.images.generate(), accepting model (dall-e-2 or dall-e-3), a text prompt, size (1024x1024, 1792x1024, or 1024x1792 for dall-e-3), quality (standard or hd), and n (number of images). The response returns a list of image objects with url or b64_json. Image editing uses client.images.edit() to modify existing images with a mask. client.images.create_variation() generates variations of an uploaded image.

The below example shows ShopMax India generating a product banner for a Diwali electronics sale and downloading the result as a PNG file.

It gives the following output,

Generated image URL: https://oaidalleapiprodscus.blob.core.windows.net/private/ ...

DALL-E 3 automatically revises your prompt for safety and quality - log response.data[0].revised_prompt to understand what was actually generated. Use quality=hd for hero images on landing pages and standard for bulk thumbnail generation to manage costs. Store generated image URLs in your CDN quickly as OpenAI URLs expire after one hour. For product images, add brand guidelines to the prompt (colour palette, font style) to keep visuals consistent across campaigns. Always review AI-generated images before publishing to catch brand or cultural mismatches for the Indian market.
