I REALLY NEED HELP PLEASE!!!!

Edit: Whoops, didn't see photo:
Same idea as below, just replace text with photo.

Hold your finger on the text you want to copy/paste. Options will pop up. Press select, or select all. Drag the blue markers, then click copy.

Tap you finger where you want to paste. Options will pop up again: press paste.

I think you double tap the photo you want, and it gives you options. Or you press and hold the picture.
