ImagePathcher.ps1: You cannot call a method on a null-valued expression

In my environments, I use MDT and/or WDS in many cases. Here is always the problem of updating images, because it takes a lot of time. For this reason, I was looking for a script, which would do the same work as I, but without losing my time.
Imagepatcher PowerShell script from CodePlex (http://imagepatcher.codeplex.com) was the perfect solution for me, but not in the last months. I think that the problem occurred after I upgraded my environment to Windows Server 2012, but I am not sure. Anyway, when I tried to execute the script, I received the error that there is something wrong with the saving of downloaded files. I analyzed the script and found that something is not working properly when combining the name from few variables.
I repaired the issue and you can download the new imagepatcher.ps1 from here.
