How to attach downloaded file to email? (webmail on chrome)

I download a file (PDF) from a website.
I open NTL world/virgin media web mail through the chrome browser.
I compose a new e-mail message and press a paperclip button to attach a file.
A small window opens with the title "Choose an action" with four options in it: Camera; Camcorder; Choose music track; Gallery.

My question is, how do I find and attach the file which I downloaded at the start of this process.

Thanks,
John

First have you tried es file explorer and gmail? In gmail click the PIC icon it will ask add attachment the locate the PDF it should ask add file normal way /android way click yes it should work.

Thanks for that. I will try that out. I presume that you mean I can then e-mail it to myself at my other e-mail account (ntlworld)?
