Ideal Image Upload Website? (tips please)

Whatsup!
I'm in the process of creating a 'perfect image upload' website.
So anyone, anywhere, at anytime can upload any size image, no restrictions, no signups. (perfect for uploading images easily of cars, mods etc...)
I want to know what people who use this type of service daily, feel these type of websites need to better accompany their users.
Anyone post there 2 cents, or any ideas they have that would make this type of website a top tier service.

To start this off, i'll explain general ideas i have already implemented.
1. No Signups
2. Super Fast Image Loading
3. Linking to anywhere/anysite
4. Personal accounts, that will hold all your images under your own sections.
5. Any type of image is fine, no restrictions

Rest are up to you, if you have any ideas, post them here.
Thank you
