This guide walks through installing WPI YouTube Thumbnail Downloader on a standard cPanel shared hosting account. The entire process takes under ten minutes.
Extract the downloaded archive and upload the full contents to your hosting account, typically inside public_html or a subdomain folder. Any standard FTP client or the cPanel File Manager will work.
Open includes/config.php and update the SITE_URL constant to match your domain, then adjust SITE_TITLE, SITE_DESCRIPTION, and pricing constants as needed.
Folders should be set to 755 and files to 644. No folder in this script requires public write access for the core thumbnail feature to work.
Confirm your hosting account is running PHP 8.0 or newer from the cPanel "Select PHP Version" tool, and that the curl extension is enabled.
Visit your domain, paste a public YouTube link into the demo form, and confirm thumbnail results appear correctly before going live.
Replace the placeholder domain in robots.txt and sitemap.xml with your live domain so search engines index the correct URLs.
