Email Issue

I've noticed that even when I send out an email to a gallery with a lot of people registered, it sends the email multiple times, even though it says it will only send it to each person once.  

Also, when I try to insert an image into an email, it doesn't show up for the receiver.  Is there a certain file type I need to use?

I won't send send multiple emails to the same email address when sending gallery invites unless something on the server is causing it to stop and restart. If you are sending to more that like 20 people you should enabled automated messages so it sends out only so many at a time. 

For the image in the email, you probably have a space or spaces in the filename which the email program is encoding which makes it not found. You need to make sure the image you are uploading has no spaces or special characters. 

Yes, I did have spaces in the file name.  Will change that for next time.

I'm also having issues where I choose to only send emails to those who placed orders, but emails went to everyone.
