I am using 'SetRotation' move a character up,down,left and right. I am also swapping image each time (so that they 'look' up,down,left and right). However, my images are chagign their orientation. How do I swap image, make the actor move but stop the orientation of the image from changing? Example code I am using below: 
move(2);        
        if (Greenfoot.isKeyDown("right"))
        {
            setRotation(0);
            setImage(right);            
        }    
        if (Greenfoot.isKeyDown("down"))
        {
            setRotation(90);
            setImage(down);            
        }
        if (Greenfoot.isKeyDown("left"))
        {            
            setRotation(180);
            setImage(left);
            
        }
        if (Greenfoot.isKeyDown("up"))
        {
            setRotation(270);    
            setImage(up);
                   
        }

I think you should turn first and then move. After that, you can set the rotation back to 0. Or you just use the 'setLocation' method instead of rotating and moving. Or you turn the images.

I tried setting the rotation back to 0 but it didn't work. Could you show me an example of what my you think my code should look like?

Did you try it like this? 
//remove line 1
//rest of your code
move(2);
setRotation(0);

Excellent, I'm almost there. Left and right are fine, but any ideas on the move setting for up and down? 
if (Greenfoot.isKeyDown("right"))
        {
            move(2); 
            setRotation(0);
            setImage(right);     
            setRotation(0);
        }    
        if (Greenfoot.isKeyDown("down"))
        {
            move(2); // ?????
            setRotation(90);
            setImage(down);   
            setRotation(0);
        }

I meant it like this, not every direction on its own: 
if (Greenfoot.isKeyDown("right"))
{
    setImage(right);            
}    
if (Greenfoot.isKeyDown("down"))
{
    setRotation(90);
    setImage(down);            
}
if (Greenfoot.isKeyDown("left"))
{            
    setRotation(180);
    setImage(left);
}
if (Greenfoot.isKeyDown("up"))
{
    setRotation(270);    
    setImage(up);    
}
move(2);
setRotation(0);
