Both modern cameras and phones take very large photos. (My phone takes large photos, but they have lousy resolution.) What you have to do is reduce the resolution (Most computer screens can't display over 96 dpi anyway.) or the size of the photo (usually expressed in inches). Any of several computer programs will reduce the resolution on a digital photo. I use an old Microsoft program called Picture It! to reduce mine. You can also use Paint, a program that comes with Windows. It's under Windows Accessories. I usually reduce the resolution, not the size of the photo. I use 96 dpi, and don't have any trouble posting them to any site I use, including this one.
