hey there - I can help you - this program is really REALLY simple - and free - some people have trouble with the other but even beginners usually can resize with this one

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
if you have any problems you can pm me and I'll be happy to help
