I should add that I've tried this on both the latest Galaxy from GitHub
running locally as my development server, and with the current stable
release at http://usegalaxy.org

Also the "Screenshot" button has a camera icon (makes sense). I'd
like a "Save" button (using the disk icon) as well or instead. Meanwhile
the "Draw" button (used in steps 4, 6, 9) has a disk icon which seems
somewhat confusing to me (it doesn't save - it takes you to another
interactive page within Galaxy).
