Assuming you have created your own user management structure and each user is 
an OzoneCompatible the following would apply:

If the total number of users are less tan a couple of thousand then any 
standard Map implementation is fine.

If the total number of users might be bigger than that you should consider 
looking at the (still experimental) persistant collections module.

If you are using the User object in Ozone things are slightly different since 
a User is a plain serializable and hence storing several thousands of them in 
a Memory-only Map is probably not a good idea (though it might still be OK 
since User is a pretty light-weight Object).

Yes Blob would be a good choice. Small pictures can alternatively be stored as 
a byte[].
