The way i do is that i click on Post Reply - scroll down and click on Manage Attachments - then click on Choose File ( mine are in Gallery on my phone) - click on photo you want - then click on Upload and wait till uploaded then click on Close This Window top right which will take you back to your post with photo attached. You can then Submit Reply or view it first.

I believe that there are other ways of doing this but that's the only way i know.
