Build An AI Image Generator Website in HTML CSS and JavaScript

Sites like Midjourney and DALL-E have acquired critical prominence as of late or years for their capacity to produce inventive and creative pictures utilizing computer based intelligence. In the event that you’re a fledgling web designer, have you at any point considered making your own variant of a man-made intelligence picture generator site? The incredible news is that with the assistance of just HTML, CSS, and JavaScript, you also can construct a site like Midjourney or DALL-E.

Assuming you’re new, Midjourny and DALL-E are simulated intelligence picture age sites. They utilize an AI model to make pictures in view of text depictions. Clients can enter their ideal picture brief, and these sites will produce a comparing picture that matches the portrayal.

In this blog entry, I will give a bit by bit guide on the most proficient method to fabricate your own site for creating man-made intelligence pictures utilizing HTML, CSS, and JavaScript. The site will be assembled completely without any preparation utilizing unadulterated JavaScript. In this way, as a fledgling, you can acquire viable experience by applying your recently educated HTML, CSS, and JavaScript abilities to genuine web projects.

On this custom simulated intelligence picture age site, clients enter their brief, pick the quantity of pictures they need to create, and click the “Produce” button. The simulated intelligence will then, at that point, make pictures in light of the client brief. To download each picture, the client can tap on the relating download button gave.

Steps to Build AI Image Generator Website HTML & JavaScript

To build an AI image generator website using HTML, CSS, and majorly vanilla JavaScript, follow these simple step-by-step instructions:

  • First, create a folder with any name.
  • Create a file called index.html to serve as the main file.
  • Create a file called style.css for the CSS code.
  • Create a file called script.js for the JavaScript code.
  • Finally, download the Images folder and put it in your project directory. This folder contains default showcase images for the website. You can also use your own images.

To start, add the following HTML codes to your index.html file.

<!DOCTYPE html>

  <meta charset="UTF-8">

  <section class="image-generator">
    <div class="content">
      <h1>AI Image Generator Tool JavaScript</h1>
      <p>Convert your text into an image within a second using this
        JavaScript-powered AI Image Generator tool.</p>
      <form action="#" class="generate-form">
        <input class="prompt-input" type="text" placeholder="Describe what you want to see" required>
        <div class="controls">
          <select class="img-quantity">
            <option value="1">1 Image</option>
            <option value="2">2 Images</option>
            <option value="3">3 Images</option>
            <option value="4" selected>4 Images</option>
          </select>
          <button type="submit" class="generate-btn">Generate</button>
        </div>
      </form>
    </div>
  </section>
  <section class="image-gallery">
    <div class="img-card"><img src="images/img-1.jpg" alt="image"></div>
    <div class="img-card"><img src="images/img-2.jpg" alt="image"></div>
    <div class="img-card"><img src="images/img-3.jpg" alt="image"></div>
    <div class="img-card"><img src="images/img-4.jpg" alt="image"></div>
  </section>
</body>
</html>

Next, add the following CSS codes to your style.css file to make your AI image generator website beautiful and user-friendly.

At long last, add the accompanying JavaScript code to your script.js record to make your simulated intelligence picture generator site useful. This code handles different capabilities, even audience members, input taking care of, Programming interface calls, picture delivering, and so forth. to produce artificial intelligence pictures in view of client prompts.

const generateForm = document.querySelector(".generate-form");
const generateBtn = generateForm.querySelector(".generate-btn");
const imageGallery = document.querySelector(".image-gallery");

const OPENAI_API_KEY = "YOUR-OPENAI-API-KEY-HERE"; // Your OpenAI API key here
let isImageGenerating = false;

const updateImageCard = (imgDataArray) => {
  imgDataArray.forEach((imgObject, index) => {
    const imgCard = imageGallery.querySelectorAll(".img-card")[index];
    const imgElement = imgCard.querySelector("img");
    const downloadBtn = imgCard.querySelector(".download-btn");
    
    // Set the image source to the AI-generated image data
    const aiGeneratedImage = `data:image/jpeg;base64,${imgObject.b64_json}`;
    imgElement.src = aiGeneratedImage;
    
    // When the image is loaded, remove the loading class and set download attributes
    imgElement.onload = () => {
      imgCard.classList.remove("loading");
      downloadBtn.setAttribute("href", aiGeneratedImage);
      downloadBtn.setAttribute("download", `${new Date().getTime()}.jpg`);
    }
  });
}

const generateAiImages = async (userPrompt, userImgQuantity) => {
  try {
    // Send a request to the OpenAI API to generate images based on user inputs
    const response = await fetch("https://api.openai.com/v1/images/generations", {
      method: "POST",
      headers: {
        "Content-Type": "application/json",
        "Authorization": `Bearer ${OPENAI_API_KEY}`,
      },
      body: JSON.stringify({
        prompt: userPrompt,
        n: userImgQuantity,
        size: "512x512",
        response_format: "b64_json"
      }),
    });

    // Throw an error message if the API response is unsuccessful
    if(!response.ok) throw new Error("Failed to generate AI images. Make sure your API key is valid.");

    const { data } = await response.json(); // Get data from the response
    updateImageCard([...data]);
  } catch (error) {
    alert(error.message);
  } finally {
    generateBtn.removeAttribute("disabled");
    generateBtn.innerText = "Generate";
    isImageGenerating = false;
  }
}

const handleImageGeneration = (e) => {
  e.preventDefault();
  if(isImageGenerating) return;

  // Get user input and image quantity values
  const userPrompt = e.srcElement[0].value;
  const userImgQuantity = parseInt(e.srcElement[1].value);
  
  // Disable the generate button, update its text, and set the flag
  generateBtn.setAttribute("disabled", true);
  generateBtn.innerText = "Generating";
  isImageGenerating = true;
  
  // Creating HTML markup for image cards with loading state
  const imgCardMarkup = Array.from({ length: userImgQuantity }, () => 
      `<div class="img-card loading">
        <img src="images/loader.svg" alt="AI generated image">
        <a class="download-btn" href="#">
          <img src="images/download.svg" alt="download icon">
        </a>
      </div>`
  ).join("");

  imageGallery.innerHTML = imgCardMarkup;
  generateAiImages(userPrompt, userImgQuantity);
}

generateForm.addEventListener("submit", handleImageGeneration);

If it’s not too much trouble, note that your site is as yet unfit to create man-made intelligence pictures since you have not given your Programming interface key in the OPENAI_API_KEY variable. We’re utilizing OpenAI Programming interface to create pictures. So to get a free Programming interface key from OpenAI, pursue a record at https://platform.openai.com/account/api-keys

” Recollect that when you pursue OpenAI, you’ll get a free $5 kudos for your Programming interface utilization. On the off chance that your record is more seasoned than 90 days or the credit runs out, you’ll require a paid record or make another one with another number to continue to utilize the Programming interface. Your Programming interface use and termination date can be found on the record’s use page.”
