PHP Image Uploader

This is a simple and lightweight image uploader written in PHP.

The PHP script saves an image from a POST-Request to a folder and sends you the URL to access the image when being called.

All images/files can embed in applications such as Discord/WhatsApp.

Setup

1. Copy the upload.php file and upload it to your web server (e.g. /var/www/website/upload.php).

2. Customize the script:

   • Line 3: Exchange YOUR_UPLOAD_SECRET with your upload secret (for example random generated string e.g. of 20 characters).

   • Line 4: Exchange UPLOAD_DOMAIN with the domain of the upload script (e.g. http://yourdomain.com/upload.php)

   • Line 5: Optional: Add a redirect URL, that you get redirected to, in case someone calls the website without an image uploader: Exchange REDIRECT_URL with this URL.

3. Download the ShareX.sxcu-File (if you want to use ShareX) or the ShareNix.json-File (if you want to use ShareNix) from the repository, and customize the custom uploader settings to fit your configuration of the upload.php-Script.

   Do the following changes whether what tool you are using:

   • ShareX
     • k = Upload secret
     • Request URL = API URL (e.g. http://yourdomain.com/upload.php)
     • Optional: d = file name (Optional!)
   • ShareNix
     • key = Upload secret
     • RequestURL = API URL (e.g. http://yourdomain.com/upload.php)
     • FileFormName = file name (Optional!) Run the file after saving your changes.

Troubleshooting

Some errors you may encounter:

Error 404

Make sure you call the PHP script, and not some other website.

Make sure your Apache/Nginx server is running.

Sorry, your file could not be uploaded.

Make sure you have PHP 7.4 installed & that the service is running (systemctl status php7.4-fpm).

Make sure your PHP script has permissions to create files (sudo chown -R www-data:www-data /var/www).
