How can I send a set of photos from iPhoto using my gmail address?

I can email photos from iPhoto as follows:

1. Click on an event to open the folder.


2. Select photos (with shift and command).


3. Choose Email... from the Share menu.

This will send an email from my @me.com address.

How do I send photos from another email address (such as gmail)?

Of course I understand that I can Reveal in Finder... each photo individually and attach it to an email message. I can also run ImageMagick mogrify on the images and then send the result. I am looking instead for a quick method that lets me just click to select the photos and also gives me the option of sending down-sampled versions of the photos.
