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

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

Some errors you may encounter:

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

Make sure your Apache/Nginx server is running.

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).
