Can I export a PNG image from Word?

If it is a Word2007 or 2010 file, you can access the images directly:

1. Using a copy of the document (so you don't accidentally screw up the original), change the .docx extension to .zip
2. Using Windows Explorer or your favorite compression application, explore the zip file contents
3. The images will be in a subfolder YourFile.zip/word/media/image1.png, image2.png, etc.
4. Copy-paste that image to wherever you want.

This also works with PowerPoint and Excel.

If you own PowerPoint:

• mark the picture in word and hit ctrl-c to copy it into the clipboard
• open powerpoint and insert the picture there with ctrl-v
• right-click the picture and select "save as picture

another solution without powerpoint is to save the word file as web page (*.html), see here: http://www.techrepublic.com/blog/itdojo/save-images-in-microsoft-word-documents-as-separate-files/135
