IE, How to know if image is loaded

Hey.

During my simulation with IE.au3, i need to check that an image is fully loaded. It's created with PHP and it's dynamic.

I can't show u exactly the website cause it's internal only, but it's the same thing as:

http://usb-online.fr/file-download-c30MTA0Mg.html

So it's an image, and i want to know if it's loaded or PHP answered error.

I don't really know how to do.

First thing i thought was to try to get the weight of the image. For example in IE i can Right Click, Properties, and there is a line Weight=XXXX octets

Maybe the size would be nice too, so do you know how i can access these informations with IE.au3 without InetGet the link?

Maybe i can insert javascript in head to return the size?

This is what i tried : 

#include <IE.au3>
$oIE = _IECreate("http://usb-online.fr/file-download-c30MTA0Mg.html")
$openfile = FileOpen(@ScriptDir & "\image.jpg", 2)
Filewrite($openfile,_IEPropertyGet($oIE,"innerhtml"))
FileClose($openfile)

But Ie wants to download the file or displays <img src="http://usb-online.fr/file-download-c30MTA0Mg.html"/>

Thx for advises,

Tim

The link you provide attempts to download an image to disk, after answering a download prompt. The questions you ask are about an image being fully loaded in the browser. You'll need to describe your scenario better before we can help.

Something about the test page you've created results in a page with different content based on whether the URL is typed in manually or if the page is created with _IECreate()

manual:

<HTML><HEAD>
<META content="text/html; charset=windows-1252" http-equiv=Content-Type></HEAD>
<BODY><IMG src="http://usb-online.fr/file-download-c30MTA0Mg.html" width=677 height=384></BODY></HTML>

_IECreate():

<HTML><HEAD></HEAD>
<BODY leftMargin=0 scroll=no topMargin=0><EMBED height="100%" type=image/x-png width="100%" src=http://usb-online.fr/file-download-c30MTA0Mg.html fullscreen="yes"></BODY></HTML>

I found a solution so here it is.

You just have to use the .complete property of the image to know if it's fully loaded.

$oImage = _IeGetObjByName($oIE,"myImage")
if ($oImage.complete) Then ...
