forgot to include requests package as requirement, replace PIL with Pillow, a well maintained version of PIL lib
Watermark is now Truetype with customizable font and location.
resizeImageAndApplyWaterMark is renamed to
compressImageAndApplyWaterMark, since the resize is actually done by the
capture function supported by the Pi camera.

Optionally support exif data. The data was discarded at compression but
now automatically restored. Updated the README accordingly.
fixed the Camera always on issue. Close the camera after each shot.
there should be 2 sec warm up timer before a capture take place.
i obvously forgot to read the documentation.
git doesn't link leaving a empty line after code block in enumeration text
refine readme a bit
Merge pull request #5 from paulshi/master
