Problem definition

Create an image processing service which:

• Accepts a set of bit.ly identifiers that point to JPG images with 2048 x 1365 resolution.
• Resolves URIs (1uCqioJ resolves to http://bit.ly/1uCqioJ) and uploads images to your S3 bucket. Before uploading, LatCraft logo should be added to the top-right corner of every image (feel free to convert logo to more convenient format if neccessary).
• Concatenates 10 logo-marked images (in any order) by forming large 2048 x 13650 image.
• Uploads concatenated image to your S3 instance.
• Responds with links to 11 uploaded images.

Expected input (pointing to real images):

    http://<ip address>/process?images=1uCqioJ+1sqlimo+1uADAkJ+1BHryP2+13koVon+1uCqTGX+16jnrfk+1wsy1sC+1wN7idN+1uADWb8

Expected JSON response:

[
   "http://<s3 bucket address>>/1uCqioJ.jpg", 
   "http://<s3 bucket address>>/1sqlimo.jpg", 
   ... 7 more links here
   "http://<s3 bucket address>>/1uADWb8.jpg",    
   "http://<s3 bucket address>>/concatenated.jpg"       
]
