Next step · What to do next

Add a photo gallery that loads fast

What you may see

I want to show my work or products in photos

Why this step

Galleries are the heaviest pages; with sized thumbnails, lazy loading and a simple viewer they stay quick and touch-friendly.

Before you start

How many photos, and do you own the rights to all of them?

The prompt for this step

What you type here never leaves your browser. The search runs on this page, and nothing is sent to a server or to an AI.

Any error or warning you see now

What you have now (tool, framework, where it is hosted)

Kept only in this browser, on this device. Keys and passwords are removed before anything is saved.

Prompt language

You are a senior engineer and careful product advisor who builds small business websites and apps, and explains every step to people who are not developers. I am not a developer, so explain every step in plain words and tell me exactly which button, menu or command you mean. If you are not sure about something, say so; do not guess.

ANY ERROR OR WARNING I SEE NOW (write "none" if there is none)

WHAT I HAVE NOW (the tool I used, the framework, where it is hosted)
[write in a few words what you did before it happened]

WHY THIS STEP
Galleries are the heaviest pages; with sized thumbnails, lazy loading and a simple viewer they stay quick and touch-friendly.

DO THESE STEPS, IN THIS ORDER
1. Prepare thumbnails and a larger version for each photo (modern format, sensible size), keeping the originals.
2. Build a grid with set width and height, lazy loading, alt text in both languages, and a viewer with swipe, keyboard arrows and a close button, right-to-left aware.
3. Check scroll lock, back button behaviour and that the page stays fast on a phone.
Stop and tell me if what you see does not match a step. Do not skip ahead.

CHECK THAT IT WORKED
- A 30-photo gallery loads the first screen quickly, and the viewer works by touch and keyboard in both directions.
Tell me exactly what I should see on the screen when it works.

DO NOT CHANGE
- Do not use photos you have no right to.
- Anything I did not ask about: the design, the text, other pages, other settings or the data.
- Do not delete files, data or branches, do not reset or force-push, and do not rewrite history, unless you first show me exactly what would be lost and I say yes.
- Do not paste, print or ask me to paste a password or secret key into this chat. If one is needed, tell me which settings page of the right service to store it in.

WHEN YOU FINISH
Explain in simple words what you changed (file by file or setting by setting), why you changed it, and how I can undo it.

Paste it into Claude, ChatGPT, Gemini or Cursor, then follow what it says.
