If you are just using "Select all" from the Edit menu in the browser and copy, this will probably will not copy images.
The choices are, copy the text and "Save as" each image separately, or goto File, "Save web page as", (or similar, depending which browser).
Windows XP Sp 2 Home Edition. A one or two screen subject with a printer friendly view I select ALL and it copies only the text to the clipboard. The graphics are indicated with message "Image not available".
