This is how to resize your photos:
I use a program called Irfanview. You can find it at:
IrfanView - Official Homepage - one of the most popular viewers worldwide
It is a free/donation optional download. To reduce the size of your photos in this program (and many others) do the following:
1. Go to Image (sometimes tools)\Resize Resample\ and select either 800 X 600 or 640 X 480.
2. I like to save as tractor reduced.jpg (example wording) (thus I know this is the reduced version).
The 640 X 480 may be too small to give your visual but will be lower in size. You will need to test. Usually 800 X 600 is a good photo resolution.
Sincerely,
Ikymojoe
