>I was sent a PDF with many images, but am unable to find a way to get them out. The author of the document is unavailble to get them in their original formats. I have the full version of Adobe Acrobat and I'm trying to get them in an image format. Is this possible?

If nothing else helps... set your display to best number of colors, and start doing screenshots. If you think the images had greater resolution than they show, you may zoom, take partial (somewhat overlapping) screenshots and later put them together using some good photo stitching application.
