Little Grow Picture Time Tracker

I made this little application today, that extracts exif data from pictures you make from your grow that renames and optionally downscales your pictures for making tracking your grow times easier. Also makes reports for grow journals whole lot more consistent, as you always know when in the grow timelapse exact picture were taken, regardless of when its actually being posted on forums. 
 
I made it quickly so there could be bugs and such, so bear with me ;D
 

 
Simple usage:
 
1. Click "From.." and select directory where your 'target' raw images reside
 
2. Click "To.." and select directory where your new renamed/downscaled images will be copied to
 
3. "Zero time" - time when the grow supposedly begun is being tracked as the oldest made image, your seedling in first days after crawling out of ground or new planted clone. If you don't have such image or want to specify different starting time, you can do that by checking "Begin date" checkbox and specifying your starting date from calendar.
 
4. Fourth option differentiates between two different time naming conventions - either as days or days/weeks/months.
 
5. You can prevent from unnecessary extra work of copying and/or downscaling images that are already done. If you want to have fresh go, with different downscale size, for example, you can either specify different "To" folder, or delete out old files from your "To" folder OR uncheck that checkbox.
 
You need .net framework 4.0 to run this nonsense, should not be a problem, unless you keep your computer terribly out of date...
 
If have also attached source code, if you want to see uncommented horrors.
 
This has not been tested on any machine but my own, so i hope it works for you, have fun with it and post any pitfalls or improvements you think you could use... ;D
