Without CSS it still displays the encrypted image with the Encryption / Decryption - technique, doesn't it?

Without JS, it's all bad :(. But, with JS, and without CSS, I can just right-click¸ view-image. This gives me the base64 in the address bar (Firefox).

A simple save page later, and I get your image. Bang.
