How to get to work input multiple in Contact Form 7 or some other plugin or Wordpress wp_mail?

Good night. And until I start, i want to apologize for my poor English.

So, at site i have the contact form which use CF7 handler. By design my feedback mail form should be able send several attachments (3-4 images) to my email, but unfortunately after some tries do this i understand that the CF7 can't work with input multiple (plugin able to add just one by one attachments, not at all in multiple selection), and i dont know how fix it.

Maybe someone who already had similar issue and find an answer can advice some alternative variant (another plugin fo example or some code).

Thank you.
