常见问题:
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.
