Don't downsize them from your camera. Downsize them with software. The camera is designed to get the best, sharpest image possible, which means large file sizes. You WANT this for pictures you take of family, activities, holidays, memories, etc. because you will get the best possible prints. However, any time you want to post a picture anywhere on the internet,whether it's here or Facebook, the file needs to be 1 mb (1000 kb) or less. So resizing with software is your best bet. The ones listed above should work. I use Photoshop, which allows me to do other things besides resize, but it's not free.
