Ah, but you can access anything in iPhoto in the "open file" dialog that opens up when you go to attach a file in gmail. It's in the left sidebar under "media", from there you can get to anything in iPhoto organized in the same way they are in iPhoto (here is a screenshot: http://civicit.com/~tvon/files/osx-open-file.png).
Obviously though, you didn't find this, and I can see how that could be a bit obtuse if you expect to browse "Pictures" and find a bunch of image files.
