Once an image is included in a Word document, it is embedded as part of the file.  If you would like to use an image that is part of a Word document, luckily there is a quick and easy way to extract and save images from Word.  Saving a Word document as a Web page (from Word 2000 on) will separate the text from images as separate files.   

To save your document as a Web page, select (File > Save as) then choose Other Formats.  From the pull-down menu, next to Save as type:, select (Web page *.htm; *.html), then save.  Two components will be saved; a folder, which will contain the image files along with a separate .htm file. Find the image files you’d like to use and you may delete the rest, since you will still have the original Word document.
