Resize pics to print ??

[dozergirl]

Hey all, newbie here! I'm not very good with Cameras, but find it very interesting. I have a Nikon Coolpix L20, don't care for it at all :thumbdown: However, I have a photo frame that needs 8- 4" X 4" pictures to fill it. My question is: What is the easiest way for a beginner to print out custom size pics? Can I print then from my home printer, or is it better to let someone else print them? Any help is appreciated as I have a $70 picture frame to fill! Thanks to all
