Where should I store users' uploaded images?-Folder in FTP or somewhere else

Hi,

In my site I am giving an option for the users to upload their photo and it will appear in their  account page.

At present I have created a folder called 'Userimages' together with the other folders in my FTP, and when

a user uploads his image it will be stored in that folder.

Is it the way I should store the images or should I go for something else?

Thanks
