This feature also happans to occur automatically with a lot of different forms of digital picture taking and sending equipment. (in some cases it cannot be turned off)
Which is reason #2 why I shy away from advising anyone to use cams/phones, or pics in any online capacity...especially when congressing with someone you have so much as never met in real life and therefore cant possibley really know them or their true intentions for you or the pictures you provided in good faith.
