BufferedImage img = ImageIO.read("myimage.gif") ;
System.out.println("image width: "+img.getWidth()+" height:"+img.getHeight());

Need import any class file?

why "Undefined variable or class name: ImageIO" ?

[mynetplayer]

What means
"Can't connect to X11 window server using ':0.0' as the value of the DISPLAY variable."

[graviton]

of course you need to import the classes BufferedImage and ImageIO.
since my eclipse does such automatically, i can't tell you where to find them.
just go to the javadoc and browse to that classes and include their full package+class names in the import.

Can't connect to X11 window server using ':0.0' as the value of the DISPLAY variable.

hmm, are you starting the code from a unix-shell?
if so, you will not be able to work on images, since java needs a display-driver as used on graphical environments to work with images.
as far as i know there are some "fake" drivers that java can use to create a virtual display console to work with images. but you will have to google to solve that.
