These functions should have comments describing what they do and names for their
parameters. Also, it might be best if these were all part of a Downloader class,
which could handle all the steps here together.

+NSData* downloadChromeAsData(NSURL*);
+NSString* getDownloadsFilePath();
+void writeDataToDisk(NSData*);

This name needs to be longer and more descriptive, specifically about what the
data is and where it gets written. Perhaps something like
'writeChromeImageToDownloadsDirectory'? Although that kind of function sort of
suggests that a class might be better here.
