Problem with email uploads

http://imgur.com/JlcFk4H

I use email upload feature when I have to batch upload lots of smaller images. The upload form is still buggy and a lot of files fails during the process making it painful to use. And of course, these file names disappear after a couple of seconds making it hard to keep track. 

Now the email system has the same problem. Sometimes one or two files would not be uploaded as shown in the image above. And the email response would not clarify which image(s) failed. 

This means I have to delete all the uploaded photos and restart again. 

I just want a failsafe method to batch upload photos. The recent addition of captcha is adding to the misery. I have a Pro account! 

Thanks!
