Where do pictures go when you unhide them on Snapchat

It's no secret that tons of people use Snapchat for private conversations, and if there are some other conversations, videos, photos, and memories you'd want to save under the "My Eyes Only" folder, you'll get another password prompt to access this data. However, if you reset your password, then everything under "My Eyes Only" will be permanently deleted.

So i had a really important photo of a document in my my eyes only and i was trying to export it out of my my eyes only so it was already in the folder. Instead i pressed a photo of a lock saying hide and the photo dissapeared. Anybody know.how to get it back?
