Get image width and height before upload

[EnjoyNews]

Hi

Is it possible to somehow get the width and height of an image that is not
uploaded yet.

Ex.
<input name="upload" type="file" onchange="some javascript that sends the
width and height to a div like getElementById" >
So when is click browse and finds an image it will write the width and
height in a div somewhere else on the page.

So it is before the form is submittet ?

It would also be ok if it was a button you clicked after you have browsed
you image.
It just has to be before upload..

This is impossible due to security restrictions. The only way is to
first upload the file.

Thanks...

But how can I upload the file without submitting the form ?

The form must be submitted anyhow, either by a manual action of the
user or instructed by the following javascript command:

documents.forms[0].submit()

(in case there is only one form on the page)

The file must first be manually selected by the user in any case.
