HI Andre,
i have done something similar with power point, i believe you can do same with Word.
1 You need to Open your word file, which is simple process,'
2. Use Send keys Alt N P to insert a picture to your document, this will open up a Windows browse window, use that to navigate to your stored logo location.
3. Once you insert the image within document, you need to identify shape#(This is bit messy), i don't have straight way to find a shape number but if that logo is first image in your doc, your shape# would be 1. i have seen it increment in linear way so if you have 4 image/shapes in document then new image would have shape#5.
4.now you need to click on image, select format shape and note down, top margin and left margin.
5.convert this margin to points(, 1 inch = 72 points.)
6. you will have to write a code stage to position picture/logo in correct place. you can also write a small code stage to resize the picture.
This works very well. i hope this will help you.
