Yes. You need to use ordinary file i/o to establish the path to the image (this can be a hard-coded path, or entered by the user, or selected in a file browser, so you have plenty of options here). Then you create a BufferedImage object and try to read it …

Yes. You need to use ordinary file i/o to establish the path to the image (this can be a hard-coded path, or entered by the user, or selected in a file browser, so you have plenty of options here). Then you create a BufferedImage object and try to read it using the ImageIO class.
The tutorial here will help.

Or you could look into running it as a trusted applet, a bit of research on that might help you out. I've never jumped through those hoops, so I can't help you there, but it might get you there.
But a non-trusted applet can't access the local file system, period.

First of all import java.io.*;
Secondly use "d:/Winter.jpg" in filename isntead of "d:\Winter.jpg"

What is the error you're getting?

Here's one major problem with your code:
Replace this

catch (IOException e) {}

with this

catch (IOException e) {e.printStackTrace()}

why preDinosaurus Applet (AWT), who's gave you this example,

change that with JFrame (no securityManager issue), otherwise correct info about SecurityManager
