Since buying my DSLR, I have been asked to take pics here & there for folks. Now I've been asked to take pics for a neighborhood event. I'm not good enough to charge anyone for pics. But I wanted to post the pics where folks can download or order prints. With each pic consuming a lot of memory, I expect this will consume a lot of space. Is there an online website that's good for hosting/posting pics like this...preferably free? This is all new to me. So any help would be greatly appreciated. Thanks.
