To add an image slider in the WordPress block editor, install the free SlideVerse plugin, insert the Image Slider & Photo Carousel block and click Add Images. Choose slides per view, arrows, dots and autoplay in the sidebar, set different numbers for desktop, tablet and mobile, and publish — no shortcodes or page builder needed.
Before you start: prepare the images
| Rule | Why |
|---|---|
| Same aspect ratio for every image | Stops the slider changing height between slides |
| ~1600 px wide for full-width, ~800 px for a 3-up carousel | Sharp without wasting bandwidth |
| WebP or compressed JPEG | Sliders load several images at once |
| Alt text on every image | Screen readers and image search |
Build the slider
- Install and activate SlideVerse (WordPress 6.5+).
- Edit a page, click + and search for slider.
- Insert Image Slider & Photo Carousel.
- Click Add Images and select your photos.
- Open the block sidebar:
- Slider Settings — slides per view, space between slides, transition speed, loop, centered slides, grab cursor, keyboard and mousewheel control.
- Navigation — arrows and dots, and arrow position.
- Autoplay Options — turn on and set the delay.
- Effects — slide or fade.
- Add captions (below or as a hover overlay), tooltips and a link for each image if you need them.
- Switch the editor preview to tablet and mobile and adjust slides per view for each.
- Publish.
Recommended settings by use
| Use | Slides per view (desktop / tablet / mobile) | Effect | Autoplay |
|---|---|---|---|
| Full-width photo slider | 1 / 1 / 1 | Fade | On, 5 s |
| Gallery carousel | 3 / 2 / 1 | Slide | Off |
| Product photos | 4 / 3 / 2 | Slide | Off |
| Portfolio strip | 3 / 2 / 1, centered | Slide | On, 4 s |
For a gallery visitors browse, leave autoplay off. For a mood slider, use fade with a slower delay.
Performance and accessibility
SlideVerse loads its slider scripts and styles only on pages that contain a SlideVerse block, and serves them from your own site — nothing from a CDN. Sliders support touch and swipe. Autoplay pauses when a visitor hovers or focuses the slider, and stays off for visitors who prefer reduced motion.
