Clone http://weheartit.com for $2,300usd

Anyone can clone http://weheartit.com using Python and PostgreSQL? Will pay you $2,300usd to a simple version of weheartit.com.
Before we hire you, you will need to prove that you know Python by answering this question:
What does this piece of code do?
img_src.extend(['/%s' % f for f in glob.glob('static/tmp/'+`pin_id`+'.*.png')])

PM me if you want to work on this project!
