Images in an account

[divz2]

Hi everyone,

 

I am planning to create a webpage where a person can register and add images to their account. Once they are happy with the formatting of the images, they can login and buy the formatting from us.

I have few questions:

Which is the best way to save images into accounts based on username??

How can customers retrieve data when they login using their username and password??

 

Thanks a lot.
