Using custom functions to send photo with email

Using custom functions to send photo with email

I am wondering if there is a way to use custom functions to attach or display the url of an attachment that has been uploaded to the record's "Attachments" related list.

I have it set to automatically send an email after creating a Quote record and would like to have any files from the "Attachments" related list sent with it. Otherwise, I will have to manually send the email using the "more actions" > "send mail" command. 

Is this possible using custom functions? Can anyone give me a little direction if it is?
