picdir

A simple web service that allows you to upload an image and then link to a dynamically-resized version of it.

It's a useful tool for self-hosted blogs and documentation.

Configuration

• If the file password exists, it should contain a password hashed with PHP's password_hash(). The app will require a password to upload a picture.
• Because of the way router.php and .htaccess work, it should be hosted at https://www.example.com/picdir/.

Files

• router.php: Used to get rid of .php extensions. Passed to the PHP dev server, AND runs in production via .htaccess.
• index.php: The home page.
• upload.php: Upload an image and store it with a unique filename.
• resize.php: Request a resized version of an image. Computes it, and then redirects to a static file.

Data

• uploads/: Where user data is stored.
• resized/: Where resized images are cached.

Ideas

• fetch.php: Fetch image with curl?
• all.php: List all images, instead of just recent ones.
• Configure Dreamhost send mails from picdir@oilshell.org to this script too?
  • Will it respond with a URL?
  • Or maybe you can view "recently mailed"?
  • Or use a free tier of an API?
• Support multiple uploads on a page, or many in an e-mail?

Links

• JavaScript drag and drop. This would be nice but looks complex, a lot of code:

• CImage and img.php: server-side resize, crop and processing of images using PHP GD.
