Creating a Chrome Extension to Copy Image Alt Text Using GPT‑Generated JavaScript

Background: Midjourney provides a scoring module that displays two images for users to choose, rewarding the first 2,000 daily scorers with free usage time. The author noticed that each image’s Prompt is stored in the alt attribute, which is cumbersome to copy manually.

Practice – Step 1: The author described the requirement to GPT‑4, which promptly supplied a bookmarklet JavaScript snippet that logs the desired information to the browser console. After requesting a modification, GPT‑4 provided an updated version that copies the data to the clipboard, offering clear, step‑by‑step guidance suitable for a non‑programmer.

Step 2: The initial execution produced errors; the author fed the error messages back to GPT‑4. After a second iteration, GPT‑4 identified that editing the code directly in the bookmark bar altered its formatting. By creating a new bookmark in the bookmark manager and pasting the corrected code, the script ran successfully.

Step 3: Seeking alternative solutions, GPT‑4 suggested building a Chrome extension. It even proposed a fitting name, “image‑alt‑copier.” Following the detailed tutorial, the author created the necessary files, sourced an icon, and prepared three PNG resolutions, completing the extension without difficulty.

Result: The extension worked flawlessly, marking the author’s first browser‑based programming project. The experience demonstrated that natural‑language‑driven programming is now feasible and that the barrier to creating useful web tools is remarkably low.

Reflection: In the emerging AI era, tools like GPT‑4 can lower technical thresholds for tasks such as coding, design, and photography, enabling ordinary users to realize creative ideas quickly while allowing professionals to boost efficiency and elevate their work.
