and this is also a very easy program you can use for free

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 460 Pixels and it resizes it for you... SAVE YOUR PICTURES AS JPEG’S or they will not show as thumbnails.
Good luck ! If you need help just send a pm to me and I'll be happy to size them for you
