Single Page Application

Even when viewing profiles or individual images, the only page ever served is index.php. This is done by using htaccess rewrite rules to convert certain URLs into php GET statements. For example, vising img.zrmiller.com/u/testuser uses the rule

RewriteCond %{REQUEST_URI} ^/u/.+$
RewriteRule ^/?u/(.+)$ /index.php?profile=$1 [L]

to reinterpret the url as img.zrmiller.com/index.php?profile=testuser. This GET statement then triggers an include in index.php to add the contents of includes_img/page/profile.php, which handles displaying the images uploaded by the target user.

Image Uploading & Display

When images are uploaded, they have a thumbnail created automatially if the file type is supported (png, jpg, gif, webp). Uploaded files are stored outside of the root directory of the website, so they cannot be viewed directly.

To serve an image, metadata is fetched from the database, added to the reponse header, then the image file is output using php. This allows for features such as privacy settings (not implemented) or fallback images. For example, if you request a thumbnail of an image with no thumbnail, the full sized image will be served instead. If you request a nonexistant image, a generic image is served instead.

API

The website offers a simple REST API for reading data from the website. Documentation.
