Smuggler - How to hide text inside image (jpeg) files

Here is an example of Smuggler in action. There are three images, one is unaltered (after it was scaled in Gimp), the other two contain text messages.

Can you tell which is which?

You can download Smuggler at the bottom of the page. If you save the images to your machine you can use Smuggler to view the messages inside them.

Smuggler is now on Android Play Store.

Smuggler desktop program

Smuggler can run on Linux, MacOs, Windows, or anywhere that you can have Java SE installed. I use Oracle java.

Download the latest version of Smuggler - this is an executable jar file, so after downloading it just double-click. I have tried to make the interface simple and obvious.
