How to Write a Blog Post with DALL-E

DALL-E, the AI image generator developed by OpenAI, is a valuable ally for enriching your blog posts with original and impactful visuals. Rather than spending hours searching for often generic stock photos, you can create custom illustrations that perfectly match your content. In this tutorial, you will learn how to use DALL-E to generate header images, explanatory illustrations, and accompanying visuals that will make your articles more engaging and professional. Whether you are a beginner blogger or an experienced content creator, this method will save you considerable time while improving the visual quality of your publications.

Prerequisites

1.An OpenAI account with access to DALL-E (via ChatGPT Plus or the API)
2.A defined blog post topic with a structured outline
3.A clear idea of the tone and visual style desired for your blog
4.A blog editing tool (WordPress, Ghost, Medium, etc.)

Steps

Define the visual style guide for your article

Before generating your images, identify the graphic style that matches your blog and the topic. Choose a consistent style (flat design illustration, photorealistic, watercolor, etc.) and a color palette. This step ensures visual coherence throughout the article. List the visuals you will need: header image, illustrations for each section, infographics, or explanatory diagrams.

Describe 5 different visual styles suitable for a blog post about [TOPIC]. For each style, indicate the type of illustration, suggested color palette, and overall mood.

Tip: Keep the same style for all images in an article to create a cohesive and professional visual identity.

Generate the article header image

The header image is the first thing your readers see. It must grab attention, reflect the topic, and make them want to read. Use DALL-E to create a unique and eye-catching illustration. Be specific in your prompt: describe the composition, colors, style, and key elements you want to appear. Generate several variations and select the one that works best.

Create a header image for a blog post about [TOPIC]. Style [flat design/realistic/minimalist], color palette [COLORS], landscape 16:9 format. The image should show [DESCRIPTION OF VISUAL ELEMENTS] with an airy composition leaving space to overlay text.

Tip: Always ask for negative space (empty area) in the composition so you can place your title without the text being unreadable.

Create illustrations for each section

Go through your article outline and identify sections that would benefit from an explanatory visual. For each key section, write a DALL-E prompt that translates the concept into an image. Ensure consistency with the style defined in step 1. Illustrations should add value to the text, not just decorate it. Favor visuals that simplify a complex concept or show a step-by-step process.

Create an illustration in [CHOSEN_STYLE] style that represents [SECTION_CONCEPT]. The image should show [SPECIFIC_ELEMENTS] in a style consistent with the [PALETTE] color palette. Square format, [COLOR] background, with no text embedded in the image.

Tip: Avoid asking for text in DALL-E images: the typographic rendering is often approximate. Add the text yourself with a graphic tool.

Optimize and retouch generated images

Raw DALL-E images often need some adjustments before publication. Crop them to the right format for your blog, adjust brightness and contrast if necessary, and compress them for the web. If an image is almost perfect but a detail bothers you, use DALL-E's editing (inpainting) feature to modify a specific area without regenerating the entire image. Rename each file with a descriptive name for SEO.

Modify this image by replacing [AREA_TO_MODIFY] with [DESIRED_NEW_CONTENT], while keeping the same style and colors as the rest of the image.

Tip: Compress your images with TinyPNG or Squoosh before integrating them into your article. A weight under 200 KB per image is ideal for loading time.

Integrate visuals into the article and write alt tags

Place your images strategically in the article: the header image at the top, then an illustration every 300 to 400 words to pace the reading. For each image, write a descriptive alt tag that improves accessibility and SEO of your article. Mention in your article that the illustrations were AI-generated, for transparency. Check mobile display and adjust dimensions if necessary.

Write SEO-friendly alt tags in French for these 5 blog post images about [TOPIC]: [DESCRIPTION OF EACH IMAGE]. Each alt tag should be between 80 and 125 characters and naturally include the main keyword.

Tip: Always add a caption under your images with the mention "Image generated by DALL-E" to follow best practices of transparency about AI content.

Common mistakes to avoid

✗Using different visual styles for each image, resulting in an inconsistent and amateurish look for the article
✗Asking for text in DALL-E images when the engine often generates distorted characters or mistakes
✗Not compressing images before publication, which slows page loading and harms SEO
✗Generating images that are too generic and offer no added value compared to a stock photo library
✗Forgetting to fill in alt tags and captions, losing SEO and accessibility opportunities

FAQ

Can DALL-E generate images with readable text for my article?

DALL-E has limited abilities for rendering text. Recent versions (DALL-E 3) handle typography better, but the result remains unpredictable, especially in French. The best approach is to generate the image without text, then add your titles and captions with a tool like Canva or Figma for a professional and controlled result.

Am I allowed to use DALL-E images on a commercial blog?

Yes, according to OpenAI's terms of use, you own the rights to images you generate with DALL-E and can use them for commercial purposes, including on a monetized blog. However, regularly check the terms as they may evolve, and transparently mention that the images are AI-generated.

How many DALL-E images should I plan for a standard blog post?

For a 1,500 to 2,000-word article, plan for 3 to 5 images: a header image, two or three section illustrations, and possibly a conclusion or call-to-action image. The general rule is to insert a visual every 300 to 400 words to maintain reader attention and break up the layout.
