how to get image size

Your code works when I try to read the width and height of a file on the local disk

package test21;

import javax.imageio.ImageIO;

import java.awt.image.BufferedImage;

import java.io.IOException;

import java.io.File;

public class ImageTest {

public static void main(String[] args) {

//This works

int[] widthHeight = getWidth_height("C:\\someimage.jpg");

//This doesn't work

int[] widthHeight = getWidth_height("http:\\\\www.google.com\\intl\\en_ALL\\images\\logo.gif");

System.out.println(" Image Width : " + widthHeight[0] + " image Height: " + widthHeight[1]);

}

public static int[] getWidth_height(String imgPath) {

int a[] = new int[2];

a[0] = 10;

a[1] = 10;

try {

BufferedImage mImage = ImageIO.read(new File(imgPath));

a[0] = mImage.getWidth();

a[1] = mImage.getHeight();

return a;

} catch (IOException ex) {

ex.printStackTrace();

}

return a;

}

}

The code that tries to get height and width of an image on another website/ ip address throws this error:

javax.imageio.IIOException: Can't read input file!

Image Width : 10 image Height: 10

Are you sure you have access to the IP address you are querying. By this I mean, is there a Firewall , a blocked port or something that is preventing access to that IP address or the image file?
