Stanley - how to get images out of .docx...
As you know, I don't have Microsoft Word but use Open Office (OO). I made a test document in OO, inserted a photo, saved it as a .docx file and closed it. Opened the .docx file again in OO, right-clicked the photo and chose `Save graphics' from the menu. The usual type of Save dialog box came up and I saved the image to a convenient folder. When I compared it to the original image it had the same pixel dimensions, a slightly different file size, and looked identical. Thus, no need to export the image from the .docx file to any other software, just save it as above. Alternatively, you can use a longer route by right-clicking the image in the .docx file, choosing Copy from the menu and pasting it into a new blank Gimp file - but you need to size the blank file to fit the image. The first method is easier.
EDIT: I've now found an easy method for getting ALL the images out of a doc or docx file in one go, using Open Office. The details are on this web page:
