Q2: Why isn't my image displaying?

If images aren't displaying, check these common issues:

1. SSI is disabled: Ensure your page has .shtml extension or SSI is enabled for .html
2. Wrong image directory: Verify $image_dir is the correct server path
3. Wrong image URL: Ensure $image_url matches the web path
4. No images in directory: Check that images exist and are readable
5. Script permissions: Script must be executable (755)

Test the script directly:
