How could Arduino monitor #hashtag on Instagram and automatically print picture?

Howdy.

I'm by no means tech- or code-savvy for hoping one of you can help me bring my vision to life.

I have an arduino board + a Polaroid zero ink G10 printer.

I'm throwing a party next week, and to increase social chatter about my event, I would like to set up my arduino board and printer so that whenever someone takes a picture on Instagram and uses the hashtag #NYCHI, it signals the printer to print the photograph automatically.

Basically, the input is #NYCHI on Instagram, output is a printed photograph.

If someone could help me figure out what code I'll need to input, as well as what additional wires/censors I will need to make this happen, I would be eternally grateful!

And if you're interested, check out NYCHI's facebook page here: NYCHI.

Thanks!!!

Now, the bad news. You would need additional Arduino hardware, at a minimum an Ethernet shield.

You or a friend would also need to be able to code the parse routine to extract the hash tag target address. For example, here is code to parse a weather site:

Once you get the tag target(s), you must download the picture binary and manage the printer. Not a trivial task. A Due would have a better chance of doing the job, but if I were doing thus project, I would do it all with a Macbook or a Linux PC.

PS: have fun with your party.

This seems like a project which would be much easier to implement on a PC than using an Arduino. It would be very easy to write a small script that monitored the hashtag and submitted a print job when appropriate.
