Next objPage
Next objPane

Answer 1

The error is caused because your code contains a confused mess of objects.
You are attempting to use late binding for Word and yet you declare:
Dim objPage As Page
Dim objPane As Pane
Dim objWindow As Window
As you appear to be writing your code in Excel this results in these objects being:
Dim objPage As Excel.Page
Dim objPane As Excel.Pane
Dim objWindow As Excel.Window
This causes the type mismatch error.
I suggest that you avoid using late binding until you have your code fully working. Then you can change all the object declarations to As Object, if you really feel it is necessary.
Incidentally, if you are thinking that you can use the SaveAsPNG method listed in the documentation to get images of the documents pages, you can't - it doesn't exist.
