Photo Tagging App
"What the Tag is a photo tagging web app.
This application's main feature is to upload, tag, list and search photos, so you can access to your photos easier.
It's a personal project – I needed this. I didn't like Picasa's web interface, lost tags of ~600 photos thanks to Picasa, and I wanted to make a simple website that I could search my photos (actually my "internet meme folder") efficiently."
