GitHub Copilot Prompt for Creating Images
GitHub Copilot, developed by GitHub in partnership with OpenAI, is primarily known as a coding assistant, but its capabilities now extend to image generation through the integration of multimodal models like GPT-4o. Directly from your IDE or Copilot Chat interface, you can describe an image in natural language and get an AI-generated visual. This feature is especially useful for developers who want to quickly create interface mockups, icons, illustrations for documentation, or visual assets without leaving their work environment. By mastering the right prompting techniques, you can get precise images consistent with your project and ready to integrate. This guide provides an optimized prompt along with several variants adapted to your level, to fully leverage GitHub Copilot's image generation potential and accelerate your daily creative workflow.
Paste in your AI
Paste this prompt in ChatGPT, Claude or Gemini and customize the variables in brackets.
Generate a high-resolution PNG image (1024x1024) depicting [describe the main subject precisely]. The visual style should be [desired style: flat design, realistic, vector illustration, pixel art, watercolor, etc.]. The dominant color palette is [main colors]. The background should be [background description: transparent, gradient, solid, contextual scene]. Ensure the composition is centered, with [type of lighting: natural, studio, dramatic] lighting and a level of detail [high/medium/minimalist]. The image will be used for [usage context: technical documentation, user interface, blog post, presentation]. Avoid any text embedded in the image unless explicitly requested.

Why this prompt works
This prompt works effectively because it structures the request into distinct layers: subject, style, colors, composition, and usage context, which reduces ambiguity for the model. Specifying the format and resolution ensures a directly usable result. Finally, the negative constraint (avoid embedded text) prevents a common flaw of generative models that often produce illegible text in images.

Expected Output
You will get a high-quality image faithfully following the requested visual style, color palette, and composition. The image will be in PNG format at 1024x1024, ready to be integrated into your project without major retouching. The result will be consistent with the specified usage context, whether it's a UI asset, documentary illustration, or marketing visual.
Frequently Asked Questions
Can GitHub Copilot really generate images?
Yes, since the integration of GPT-4o into Copilot Chat, image generation is available directly within VS Code and on github.com. This feature uses the DALL-E model via the OpenAI infrastructure built into Copilot. Just describe the desired image in the chat and Copilot creates a visual you can download and use in your project. Note that this feature requires an active Copilot subscription and may be subject to daily usage limits.
What types of images are best suited for generation via Copilot?
GitHub Copilot excels at creating technical illustrations, icons, conceptual diagrams, simplified UI mockups, and visual assets for documentation. Flat design images, vector illustrations, and diagrams generally yield the best results. However, hyper-realistic photos of people or highly complex compositions with precise text remain weak points of current generative models. For optimal results, favor clear descriptions with a well-defined visual style.
How do I integrate images generated by Copilot into my development workflow?
Once the image is generated in Copilot Chat, you can download it directly and add it to your assets directory. For an efficient workflow, describe in your prompt the exact format and dimensions you need. You can then reference the image in your HTML, CSS, or React component just like any static asset. For projects requiring multiple variations, iterate on your prompt by adjusting style and color parameters while maintaining a consistent base. Also consider optimizing generated images with tools like Sharp or ImageOptim before going to production.

Midjourney Prompt for Creating Mockups
Mockups have become an essential part of the creative process, whether to present a logo on packaging, visualize a website design on a screen, or stage a product in a realistic context. Midjourney revolutionizes this step by generating photorealistic mockups in seconds, without the need for complex PSD files or expensive stock images. Thanks to its advanced understanding of materials, lighting, and perspectives, Midjourney produces professional-quality staging that rivals studio photography. Whether you are a graphic designer presenting a visual identity to a client, an entrepreneur looking to visualize packaging before production, or a marketer creating visuals for a campaign, mastering mockup prompts will save you considerable time. The main challenge lies in the precision of the instructions: type of support, viewing angle, lighting, environment, and level of realism must be carefully described to obtain a usable result. This guide provides optimized and tested prompts for creating compelling mockups with Midjourney, from simple product previews to ultra-realistic renders worthy of a professional shoot.
