I have a long email message come into my Gmail, often a newsletter. I click the "Display images below" link to see all the pictures, I read through it to the bottom, then see this:
[Message clipped] View entire message
So I click the "View Entire Message" link, and there are no pictures, and no button to let me switch image viewing back on again?
I get this particularly on HTML newsletters, like the PlayStation newsletter (where it does ruin it because most of the newsletter is pictures) or Meetup.com's weekly info letter (where it's not so bad as it's mainly text content).
