The issue is with this code:

Java

public Image loadImage(File file)
{
    try
    {
    	Image image = ImageIO.read(file);
    }
    catch (IOException e)
    {
    	System.out.println(e.getMessage());
    }	
    return image;
}

It's related to scope of variable. You have defined image inside try and then trying to return the same outside it's scope, thus an error.

Try:

Java

public Image loadImage(File file)
{
    Image image = null;
    try
    {
    	image = ImageIO.read(file);
    }
    catch (IOException e)
    {
    	System.out.println(e.getMessage());
    }	
    return image;
}

P.S.: For clarity, I shared the above code with change but this still needs handling around an image object which is not defined in case of error and will be returned. Please make sure you handle the same.

Look at your code:

Java

public Image loadImage(File file)
{
    try
    {
        Image image = ImageIO.read(file);
    }
    catch (IOException e)
    {
        System.out.println(e.getMessage());
    }
    return image;
}

And think about scoping rules: where is image defined? Where are you using it?

Because you declare image inside the try block, it goes out of scope at the matching close curly bracket, so it isn't available when you hit the return statement.
Move the initial declaration outside the try block, and you'll be fine:

Java

public Image loadImage(File file)
{
    Image image = null;
    try
    {
        image = ImageIO.read(file);
    }
    catch (IOException e)
    {
        System.out.println(e.getMessage());
    }
    return image;
}

Java

public Image loadImage(File file)
{
    try
    {
        Image image = ImageIO.read(file);
    }
    catch (IOException e)
    {
        System.out.println(e.getMessage());
    }	
    return image;
}

You are declaring the variable image inside your try block, which means that it does not exist after that line of code has been executed. Move the declaration uotside that block as follows:

Java

public Image loadImage(File file)
{
    Image image = null;
    try
    {
        image = ImageIO.read(file);
    }
    catch (IOException e)
    {
        System.out.println(e.getMessage());
    }	
    return image;
}
