I need some help to add an upload files field to the form for ordering.
I have been trying to see if i can do this through paypal whilst they check-out the order but to no avail. So will have to approach it from this angle i think.

I don't think the internal Zenphoto mail system supports attachments at all (for a good reason actually, spam and other malicous stuff...)

Had a feeling you were gonna say that.
It does make common sense to lock that down. I will need to look elswhere for a suitable solution.
Thank you for you continued help, your advice is essential.
Kind Regards
Barry

You of course can always make your own plugin independent from the interal Zenphoto setup. Mailing via PHP's sendmail or the PHPmailer class (which we have plugins for) generally does support attachments, we just did not implement it internally.
