Unless you have a photo editing program on your computer that allows you to resize for e-mail/web purposes you probably won't be able to. I have to resize most of the daytime pictures from my bushnell when I use the 5mp resolution. If I set it for 3mp I don't. I'm the one that can't seem to post more than five pics at a time. I don't know how others post more than that. I also can't seem to put pictures in a reply to post message either. I've actually started to use photobucket.com so I can post more pictures.
