This is a really elegantly simple solution and works perfectly except that you may experience an increase in 
file size unless you set the JPEGQuality before you export. Running a 50.4K jpeg through exiftool to delete 
all metadata reduced the file size to 39.4K. Importing that 50.4K image as a control in Livecode and exporting 
a snapshot resulted in a file size of 140.2K. Setting the JPEGQuality to 75 prior to export results in a file 
size of 40.6K. 

Exiftool is available for all platforms as a gui and cli tool, for those interested. As a cli tool, it can be 
use with Livecode's 'shell()' to return exif data as well as write/edit/delete it.
