My Mac Pro 3.0 Gigahertz stopped emailing photos through IPhoto. When I click on a picture, and then the mail icon, a progress bar appears on top for a split second, and then nothing happens. Checked properties to make sure mail is the default email app. Not sure what else to do. When I played around with the PlaneMailer (the app that works with gmail) that was the app that would email my pics. I uninstalled that app and ever since I am now stuck. I would like the default apple mail to email those pics out. Please help!
