how do i download a photo from "saves" on a tablet?

[Android Central Question]

i have a amazon fire tablet, and after finding a image on silk browner, i wanted to save it. a little while later, i went to it and wanted to download it. i didn't see a download button anywhere, so i followed my fathers advise and tried going to the image and pressing on it to download it. the only problem was that the image wouldn't show. what do i do, and is there any other way to download it?
