Try
this link to see if it helps you at all. Like Karen said...clear as mud. It's hard to explain.
If all else fails, or to learn more about how to resize a picture, have a look through the help files in a graphics editor. Just open the file in an editor like Photoshop, Microsoft Paint, Picasa, etc etc etc and look through the help file index.
Example:
In
Paint (most likely on your computer in the Accessories folder) click on
Help
Click on
Help Topics
Click on
Search
Enter
"resize" as the keyword and hit
Enter
Click on
Change the size of your picture
Good luck!
