How do I properly use this Image code?

Question

I'm trying to get an image's Dimension online from a URL, like the person in this question:

Java/ImageIO getting image dimensions without reading the entire file?

However, I don't know quite how to use the code of the best answer there to get the result. I want to get the image's height and width without having to load it.

What do I put resourceFile as, if I have a URL that goes to an image?

If it's online, you *can't* use a "resourceFile" or any file. — Hovercraft Full Of Eels, May 15 '12 at 01:50
You can get an ImageInputStream from the static `ImageIO.createImageInputStream(InputStream is)` and you would need the InputStream from the URL for this. — Hovercraft Full Of Eels, May 15 '12 at 01:54

See ImageIO.createImageInputStream(Object)?

Parameters:
input - an Object to be used as an input source, such as a File, readable RandomAccessFile, or InputStream.

Further, as @Hover comments:

..you would need the InputStream from the URL for this.

@Hovercraft What, you mean 'read the docs.'? (panics) Sh*t, they're on to me! – Andrew Thompson May 15 '12 at 02:00
I tried, but I'm a complete newbie at this. Thanks for your help, I got it to work after about five hours of searching for an answer! – Michael Celani May 15 '12 at 02:25
@Michael: if you try and it doesn't work, you should show us your attempt, else how can we see what you're doing wrong. – Hovercraft Full Of Eels May 15 '12 at 02:27
