I've never tried emailing photos from last photos downloaded. I se either Camera Roll or Photostream. If you a long tap you'll get the Select Select All etc menu that has Insert photo or video. Tap Insert Photo or Video and a menu will come up with a list. You can then choose an album or Camera Roll or Photostream.
I download some of my photos to my ipad2. I used to be able to email my photos to friends from the last photo roll or last photos downloaded. This no longer works ...is there something new r different that I need to do?
