App crashes after taking the first 4 photos on RPi

[joelpereira]

I've loaded the latest code on my RPi 2 by following the instructions in the wiki. The page loads but the program only takes the first 4 pictures before crashing. I don't know where or what to fix based on the error (can't find an "events.js").

Here's my log output: pi@raspberrypi:~/shmile $ coffee app.coffee (node) sys is deprecated.

Looks like I missed the imagemagick install line. Running this fixed it. sudo apt-get install imagemagick
