Transferring Screenshots files wirelessly

Hi,

I got my Kindle PW jailbreaked. I know how to take a screenshot. If I want to transfer my screenshot file to my laptop to email it or share it, I must connect my Kindle PW to my laptop physically. Is there a way to email it wirelessly from my Kindle right away? Is there a file explorer or something which i can install in my kindle then browse files, select the screenshot and send it?

Thanks in advance
