In reply to David Coley:
In the short term without getting involved in Word web settings, you should save the original images files into separate folder at the size you require, making a note of these sizes. Then upload that folder to your website. Then you will need to edit each html file and change each img tag( you can use the search function in notepad to find them easily
. I.E change this:
<img width="201" height="151" border="0" v:shapes="_x0000_i1230" src="6TheBelay_files/image006.gif">
To this:
<img width="450" height="550" border="0" v:shapes="_x0000_i1230" src="NEW_UPLOADED_FOLDER/image006.gif">
You should consider changing the picture format from .gif to jpg while you at it!
Hope this helps,
Rob
