automatically resized image attachments

On the attachments area there is a button on the right hand that reads "Photo Size", you can change it from "Reduced" to "Original". There is a small chance that you are still on the older version of Mail, if the Photo Size button is not there, check the "Options" menu to the right of the attachment's progress bar.

The option only shows up when the pictures are attached. It seems to default to small, so when you attach files, you need to do it twice. First we small and then again as the size you want. Pretty lame.
