Generate Blog Post Images With Dall E 3 for Free: A Step-By-Step Guide

Generating blog post images with AI can save you hours of design work. With our custom GPT, you can generate blog post images and thumbnails in seconds. A ChatGPT Plus subscription is needed to access our free tool.

Step 1: Identify the Topic of Your Article

Before generating your blog post image with AI, have a clear idea of what your article is about. This will help the GPT to express your article using visuals.

Step 2: Open Our Free Custom GPT

We created a free custom GPT to make it as easy as possible to generate blog post images with AI for your articles. Use it for free here.

Step 3: Craft Your Prompt

To generate great results, be specific about elements like color, style, and imagery. For instance, "blog post thumbnail about digital marketing with a laptop in the center" is more effective than just "blog post image marketing". 

I recommend structuring your prompt after the following formula: 

"blog post thumbnail" + [article topic] + [color scheme]

Simple but effective prompt.

Step 4: Choose a Color Scheme

You can either choose a color scheme that fits your brand or let the GPT choose a color scheme that suits the topic of your articles. The more detailed your color choice, the better the results. For instance "navy blue gradient" is better than "blue color scheme".

Step 5: Refining Your Blog Post Image

Don't settle on the first result. Often you need several iterations until you create the perfect blog post image for your article. Often you have to add or remove visual elements that don't fit the topic of your article. My advice is to always try to remove text via prompts for the best results.


Tips for Better Results

  • Use descriptive adjectives: Terms like "simple" "modern," "sophisticated," or "geometric" can guide the AI to generate better results.

  • Mix your article topic with your branding: For instance, generate an image for your article paired with the colors of your brand. 

  • Simplicity is key: Less is more. Try to generate images without too many visual elements to avoid clutter.

  • Color matters: Be specific in your color choice for optimal results.


TLDR

  1. Open our free AI blog post image generator.

  2. Describe your article topic & color scheme.

  3. Refine your blog post image even further.

Using AI to generate marketing assets saves a lot of time, but often they are not very accurate. Use our premium library to create marketing assets in seconds while maintaining high-quality designs. No design knowledge is required. 

Automate your visual content creation and publishing

If you are running a business, you already know the problem. Posting content is one thing. Doing it consistently across LinkedIn, Instagram, TikTok, Pinterest, and X while keeping everything on-brand is a full-time job you did not sign up for.

Situational Dynamics is an autonomous content engine that generates and publishes on-brand social media content for you. You fill out a short brand questionnaire. The system encodes your voice, colors, and audience into a design system. From that point forward, content arrives in your inbox ready for one-click approval, and approved posts get designed, rendered, and published automatically.

  • 150 posts per month, zero manual work. Static posts, carousels, and blog content are generated and published across up to 5 platforms. You never open a design tool, write a caption, or touch a scheduler.

  • Your brand, not generic AI output. Every post is rendered through your personal design system with your exact colors, typography, and voice. No two clients produce the same visual style.

  • One-click approval from your inbox. Content ideas land as interactive email cards. Tap approve. That is your entire involvement.

Stop configuring tools. Start receiving results.
