Performance Optimization

Robo Gallery is designed to work efficiently even with large image collections. However, for best results it is recommended to follow several optimization practices.

These techniques help galleries load faster and improve overall website performance.

Use Optimized Images

Large image files are the most common cause of slow gallery loading.

Before uploading images to the gallery:

• resize images to the required display size
• compress images using optimization tools
• avoid uploading extremely large photos directly from cameras

Recommended formats:

• JPEG for photos
• PNG for images requiring transparency
• WebP for modern optimized images

Enable Lazy Loading

Lazy loading allows images to load only when they become visible on the screen.

Benefits:

• faster initial page load
• reduced bandwidth usage
• improved performance for galleries with many images

Lazy loading can be enabled in gallery settings for both Classic and Fusion Grid galleries.

Enable Gallery Cache

Robo Gallery includes a built-in cache system.

When enabled, the gallery generates cached data that allows it to load significantly faster.

You can enable cache inside gallery settings:

Gallery → Settings → Cache

Cache is automatically regenerated when gallery settings are updated.

Use Pagination or Load More

For very large galleries, displaying all images at once may slow down the page.

Instead, use:

• pagination
• load more button

These options allow images to load progressively as the user navigates through the gallery.

Avoid Excessive Hover Effects

Complex hover animations and overlays can increase rendering load, especially on mobile devices.

For large galleries it is recommended to:

• use simple hover effects
• avoid heavy animation styles
• disable hover effects on mobile devices

Use Website Caching Plugins

WordPress caching plugins can significantly improve page performance.

Popular options include:

• WP Rocket
• LiteSpeed Cache
• W3 Total Cache
• Autoptimize

These tools optimize page rendering, script loading, and caching.

Monitor Page Speed

If your gallery contains many images, it is useful to monitor page performance using tools such as:

• Google PageSpeed Insights
• GTmetrix
• Lighthouse

These tools can help identify performance bottlenecks.

Summary

To keep galleries fast and responsive:

• optimize image sizes
• enable lazy loading
• enable gallery cache
• use pagination for large galleries
• avoid heavy hover animations
• use caching and optimization plugins

Following these practices ensures that Robo Gallery performs well even with large image collections.
