Hi Russell, One of the images that got trapped was 36K. After encoding for email that's= almost 50K. Add some text and headers and it makes the 53K that was marked= on the admin safe room. If the image wasn't 36K before you sent it, then perhaps your email client = is doing a conversion. Best regards, Bob ________________________________________ From: piclist-bounces@mit.edu on behalf of Russel= lMc Sent: Wednesday, January 25, 2017 7:50 PM To: Microcontroller discussion list - Public.
