Word gives you the option to change the default folder for saving. Open Word, go to Tools, Options, File Locations. Highlight the one you want to change and click on Modify and type in the new path to that folder. I would expect Excel to have a similar option although I have not tried it. You may also find that your image editing package will allow you to do this as well but as you have not said what image editing programme you are using I can't confirm.
