[Evolution] Attaching images (with no preview)

[Jeremy Nell <jeremynell gmail com>]

I'm a newbie.  I recently converted to Ubuntu and am a creative more than a techie, so please be gentle on me. :-)

Here's the problem:

When composing a mail in Evolution, I click on on "add attachment" at the bottom of the window.  I then navigate to, say, my pictures folder.  I am presented with a list of file names and no preview window.  Unless I have memorised the file name of the image, how will I know what the image is, if there is no preview window?  Only after I've attached the image, do I see the thumbnail in the attachment bar.

I then go to my pictures folder via Ubuntu's main menu, so that I can see the images clearly, but this seems a bit clumsy.  

Am I doing something wrong?  Or is there no preview window when attaching files?
