Copy image out of Microsoft Word
If you are using Word 2007 you can open *.docx in 7-zip, since it is basically just a zip archive. Images are located in folder word\media. A bit more direct approach to saving as html but obviously won't work in older versions of Word.
Although Ctrl+C and Ctrl+V is a good approach, but a better way is to save the MS word file as webpage, and get the jpg file.
The reason I said this is because Ctrl+C and Ctrl+V will generate a resolution loss in the picture. OTOH, if you save the Microsoft Word to HTML, then all the image size, and the original picture resolution will be preserved.
Right click -> Save Picture...
