The above picture is 640 X 420 Really too big for a comment.
.jpg" width = "400"
This is what you put in to reduce the size of the picture, I picked 400, it is a good size, you can go smaller if you want, 300 is good. Notice the change to the Html. I can only put in the last part of the code or the picture will show up. Note, some pictures will end with .Gif". Also you can increase the size, however the picture will be blurry.
Here is an actual example..!
