How do I transfer photo received as an email attachment on my iPad to my Photo file?
You seem to have gotten this to work. You got the photo in the camera roll or where ever 8.4 puts the pics.
You got the copy command to do something hence you got the photo out of your email. I suspect you misunderstand what the copy command does. I have ios 7.1.2. The copy command seems to make a temporary duplicate of the photo and place you in edit mode for the photo. You have to edit the photo then the save command will appear.
To move to a different album:
Tap on the album you want to move the picture from
tap on select
tap on picture you want to move
tap on the words "add to" don't know why this isn't some icon
tap on album you want. The picture is moved.
Copy a picture from Apple's mail app seems a little convoluted to me, but this is what we have.
I use the BeFunky for all my photo editing needs. It's free. You have to start you edit from the BeFunky app not apple's Photo app.
