Gmail JPEG attachment problem

I was away on vacation for a few days, and of course, something has to break while I was away. Gmail's attachment function broke and I got flooded with help messages. An example below.

This is the original image, taken from a previous post.


When Gmail attaches the JPEG image, it becomes corrupted. And the corruption is different each time. Once in a while it even corrupts the image so badly that it becomes uncompletely unviewable.

Surprisingly enough, the corruption problem even happens with images embedded inside PDF files. I found this out when I tried to work around the image corruption problem by embedding JPEG's inside PDF files, but the PDF files became corrupted as well.

I wonder if it's affecting all attachments?
