FAQ
-
How does image preloading work?
-
Image preloading loads images in the background before they are needed, so when users navigate to pages containing these images, they appear instantly instead of loading progressively.
-
Which preloading method should I choose?
-
- JavaScript: Best for compatibility with all browsers
- Link Preload: Best performance for modern browsers
- Both: Recommended for maximum compatibility and performance
-
Can I preload images from external domains?
-
Yes, but ensure the external server allows cross-origin requests. The plugin properly handles CORS headers.
-
How many images can I preload?
-
There’s no strict limit, but keep in mind that preloading too many large images can impact initial page load performance. Use judiciously.
-
Does this work with caching plugins?
-
Yes, the plugin works well with caching plugins and can complement them by ensuring images are cached even before they’re viewed.
