To ask how on earth I post a pic here if I'm on desktop?

I need some help deciphering a statement on a certificate but can't ask here if I can't post an image of it!

Thanks! :)

I am on a desktop too. Under the box where you type replies, there should be 3 'Choose file' boxes. Click one, and then upload your picture.

Thank you, XenoBitch. I must be an absolute nitwit because I still can't see it at all.

It's down under the message box
