Image Showcase: Testing Images, Galleries and Lightbox 📸

Images make technical content easier to follow. Here’s how different image layouts look on this theme — single images, full-width, and galleries.

Single Image

A single image centered within the content area. Click to view full size with the lightbox.

Code editor on a modern development setup — Modern development environment — the exact setup used for testing this guide.

Image With Caption

Images with captions help explain what’s being shown. The caption appears below the image in a muted style.

Circuit board macro photography — Hardware-level programming requires understanding the full stack — from circuit boards to user interfaces.

Image Gallery

A gallery of related images displayed in a responsive grid. On desktop they show in 3 columns, on tablet 2, on mobile 1.

Images In Context

Images should also work within tables and other elements. Here’s a comparison table with descriptions:

Image	Description	Use case
Code screen	Development environment with split panes	General coding tutorials
Circuit board	Hardware macro photography	Low-level / embedded guides
Server rack	Data center hardware	DevOps / infrastructure posts

All images in post content are clickable. Click any image to open the lightbox overlay — a full-screen view with dark backdrop, smooth transition, and close button. Tap the backdrop or press Esc to close. Navigate between gallery images with arrow keys or on-screen buttons.

The lightbox is built with vanilla JavaScript — no external libraries, no extra HTTP requests. It lazy-loads the full-resolution image only when opened.
