Here you go - this is very easy to resize pics

Scroll to PixResizer……Download the program..it’s really small and very easy to install – Depending on the size of your image you just have to click ONE SIZE (USUALLY 50%) or 400 Pixels and it resizes it for you...
SAVE YOUR PICTURES AS JPEG’S or they will not show as thumbnails.
another is irfanview
