Use DALL-E to generate effective image for LinkedIn posts

Summary

LinkedIn posts with pure-AI images do worse than none; posts with striking text do better than none; I don’t want to hand-make them in Photoshop ... can we do better with DALL-E?

Usefulness: Practical/Productive

Update

Summer 2024: OpenAI released GPT4-o, which is specifically able to do excellent “text as images” — this experiment needs re-doing/updating.

Techniques

  • Short prompt to generate variations, pre-sized to Linkedin’s required format.
  • I’ll ask for different stylistic variations to see how good/bad the options are – but expectation is that I’ll only use the ‘pure text’ ones
  • Prompt:
    • “Generate an image sized 1200×644 pixels (suitable for posting to LinkedIn) that contains two pieces of text, a title and a body.
    • The title is: “[my 1-phrase summary of the category of post]”
    • The body is “[my 1-line summary of my post]”
    • The title and text should use contrasting colors, in a professional looking font. Generate three variations:
    • 1. Colored text and colored background with no photography and no illustration
    • 2. Stylized text and colored background with no photography and subtle illustration, the illustration should be low contrast and/or high transparency so that it doesn’t distract from the text
    • 3. Text with relevant illustration or photography

Discoveries

  • ChatGPT-4 in spring 2024 refuses: “For the requirements you’ve described, my capability is to create one image at a time. However, I can generate one of the variations you requested. Which one of the three variations would you like me to create first?”
  • FAILED: even the requests for plain text generate highly illustrated images
  • MODIFICATION: I took the best outputs, loaded them into Affinity (the low-cost, non-Adobe, alternative to Photoshop) and cleaned + edited them to fit my goals.
  • NOTE: creatively DALL-E 3 is still quite weak compared to doing photographic/stylistic work with MidJourney – and it’s vastly worse than working with a human designer/illustrator. I could literally have done better in only a little more than that time it took me to write the prompt and wait for the responses, and edit in Affinity/PS. 
  • NOTE: DALL-E completely ignores 1-line, 1-sentence, basic instructions, while stating explicitly that it’s following them.
