The only issue with having only a low resolution original comes when you want to use the image for something else, like advertising an event or club.
I have to spend so much time at work explaining to folks why their internet sized photo is not suitable for use on a sign or a vehicle wrap, banner or billboard.
Always shoot your photos at the highest resolution and lowest compression that your camera will handle. You never know when they may be needed for another purpose. Resize or crop them using your photohosting site before posting.
