Is it possible to attache files on thank you page or emails?

Additionally, is there a way to add easy referral/share page features something like attached on the “Thanks for Submitting” page or in the email after submission?

If you want to have a file attached on the thank you page, you may upload it to your own cloud service like Dropbox, Google Drive or any other and then display the link on the thank you page, this guide will help you editing the thank you page content: https://www.jotform.com/help/211-Setting-up-the-Thank-You-Page 

In emails, you can include an attachment, while setting up the autoresponder email you will find the options to attach a file, this guide will help you doing so: https://www.jotform.com/help/26-Setting-up-an-Autoresponder-Email 

Oops sorry, I sent you a blank email.
It’s actually a link that’s pictured, how do I include a link for people to copy by clicking? Is there a way to add a form field in the thank you page or email so that users can add the emails of people they want to share our product with then emails are sent to those people, or share on social media with them?
We basically are looking for a way for form fillers to share a link to our product with friends and family via a prewritten email (by us) or social media post. We are also looking for a form field for form fillers to input emails they want to share our product with and then a prewritten email (by us) will be sent to them.
Thanks!

I can suggest to check our Social Follow and Social Share widgets: How-to-Add-a-Widget-to-Your-Form

Those widgets can not be placed on Thank You page, but you could use them on your form. Also, there is an option to redirect users to different web page, for example to your social media post: Redirecting-Users-to-a-Different-Page

I’ll check that out. Thanks!
