Testing testing 1-2-3....
-Save image=its in my downloads but unusable.
-Copy/Paste=its on my clipboard but nothing happens when I click it.
-View Image=just that. A picture to look at.
-Share image=options to share on sites like facebook, messenger, emails, etc.
*sigh*
After copy/paste, try clicking somewhere else, and hold your finger down where you want to insert what you copied, and see if a Paste option pops up.
I've used Dropbox for free for a long time. I also use OneDrive and like it a bit better than Dropbox. They have a small free amount too, I pay a minimal fee for extra storage there though. Like $2 a month.
