Q:

How to copy an image from server directory to another directory in python

I am trying to copy an image from a directory on my server and paste is to another file on server.  Then I am looking to rename it. 
Here is my code (New to python)
#!  /usr/bin/python
import cgi
import os
import shutil

print "Content-type: text/html\r\n\r\n"
username = 'bytesized'
srcfile = 'http://test.com/img/default/basicprof.jpg'
dstroot = 'http://test.com/img/%s.jpg' % username 

assert not os.path.isabs(srcfile)
dstdir =  os.path.join(dstroot, os.path.dirname(srcfile))

os.makedirs(dstdir)
shutil.copy(srcfile, dstdir)

A:

I don't know what you are exactly trying (and asking) but you need to use relative or absolute paths to your image instead of urls. 
currentpath = '/img/default/basicprof.jpg'
newpathandname = '/img/{}.jpg'.format(username) 

os.rename(currentpath, newpathandname) #does not keep original file
shutil.copyfile(currentpath, newpathandname) #keeps original file
