Cheap shot - they also likely copy/paste screenshots in to Word and mail those around too, instead of just mailing the actual graphic file. :)
When I was in consulting doing software integration work, few things infuriated me more than client "bug reports" arriving in the form of an email containing a 15 megabyte MS Word doc with a bunch of un-annotated screenshots.
I really hope Google someday opens up the awesome bug report/screencap feature in Google+, that lets you highlight part of the screen and redact sensitive parts.
