Troubleshooting and FAQs
Q: My image looks blurry or pixelated—what should I do?
A: Make sure your source image is at least 1200 px wide. If you need crisp display on high-DPI (retina) screens, consider uploading at 2× width (2400 px) and let the browser downscale.
Q: The image is getting cropped—how can I adjust it?
A: Check your theme’s CSS for any fixed height or aspect-ratio settings on the 404 template. You can override them via Theme Options > Custom Codes > CSS.
Q: Will larger files slow down my 404 page?
A: Yes—optimize images for the web (compress to under 200 KB) using tools like TinyPNG or ImageOptim before uploading.
