There are many ways to encrypt a message in an image file.
The way I've seen people do this on YouTube is them just editing the image's hex coding.
Anyway, it depends on how the message is encrypted. If it is just regular text in the image, you have to get a hex editor, such as Hex Workshop, then load the image and parse the hex coding to find the message.
In most cases, it will be located in the first few lines of the hex coding and it will be just a regular string, unencrypted.
In more advanced cases I've seen, it could be located near the middle of the whole hex coding of the image, then encoded again using a method called "Base64". To decrypt this message, I had to open up the hex coding, find the Base64 encoded string (usually ends with two equal signs "=="), then I had to unencrypt the Base64 string, which is really easy. In PHP, it's just a simple command:
echo base64_decode("base64string");
?>
Once I unencrypted the base64 string, it output the hidden message.
Conclusion:
Just open the image up in Hex Workshop, and read a few lines of the hex coding. Usually the message can be found in the first few lines.

Are there any keylogger hidden in jpg or JPEG file and where could i find it?
A key logger is an application, which means it is a .exe file and it can't be hidden in a jpeg file...fyi, computer virus/es are also .exe files and can be hidden by using winzip or programs that can compress files Most often keyloggers and such are compressed into .rar files and hidden, however finding these pictures is difficult, because the entire idea is that they are hidden. sometimes there are hints on the picture, keep your eyes open. Also, the most famous of these types of pictures is the dangerous kitten hackers pack. A keylogger COULD be hidden within a picture, however you would not trigger the keylogger opening the picture, you would have to change it to an .exe, or a .rar and extract the keylogger.
