Is this a good website startup?

Im 13. Over the summer, I want to start an online business. My ultimate goal is to make six or more figures a year (become financially independent). I know it sounds crazy since im only thirteen, but it is my goal. I have some ideas such as a website where users can submit original songs, and other users can listen, rate, comment, share and chat. It will make money from selling ad space. I like this idea, but i have another idea that could be more profitable even though it has much more competition.

The idea is a website where users can store their digital photos. I still have to do some more research on this idea though. Users would either buy a free use (2gb worth of storage), a $4.98 monthly fee with a lot more gb of storage, or a yearly fee for $51.99 with a lot more storage than that. I would either hire a web design firm to create the site, or have my cousin, who is a web designer, create the site. I would have the site use a lot of security. some other features i could add to give me competitive advantage could be printing, editing, sharing, and other services all based around the digital photo storage service. Even though there are some huge competitors in this niche, I would start small, build a loyal customer base, and grow while making nice profits.

Do you think this is a good idea? Do you think it could eventually make me six or more figures a year? Should i do this idea?

Thanks.

PS. If you dont think any of these will work, what should i do as a profitable web startup?

I have sent you a Yahoo Answers email, if you’d like some help I can try point you into the right direction.
Hope to hear from you soon (:
