Why it exists
A minimal upload-and-view gallery: pick an image, upload it, browse what's there.
What I learned
Built to understand file upload handling in PHP properly — validation, storage layout, and the sharp edges of trusting user-supplied files. The kind of thing that looks trivial until you deal with MIME spoofing, oversized uploads, and orphaned files.
Status
Archived. Most of what this solved is now handled by a CDN, a few lines of policy, and a managed storage service.
