_IEImgGetCollection - HELP

[GiorgioDistribuzione88]

Good Morning
AutoIT Opens the website of IE , connect on the website and must check:
If the image loading , which in this case is called " preload.gif " And Still Present Then wait ; Otherwise if " preload.gif " has finished loading Then MouseClick .
As soon as I open the site and the image always present , AutoIT should intervene Only if the image of a stopped .

I adopted this script , you know help me?
