SodaH8r,

Can you store this image as a clob or blob in your database? Depending on 
the size of your application, you'll see performance degradation once you 
get over 10-20K items in a single directory. Storing them in a database 
will also mean you are not tied to a single machine as your application 
grows.

Finally, uploading user files to a server directory is one of the most 
common attack vectors. If you do so, make sure they are not given 
executable permissions and validate that they are truly images before 
saving them to disk.

Sincerely,
Joseph
