Idea for an image gallery with textbox

Hey there,

I am looking for an idea to realise following:
in the application, people see pictures. People descibe the picture in a textbox, and the text is saved on for example mongoDB.
After clicking on next or a button to save the description text, no one sees, what description someone already saved.

Any ideas?
I am using Blaze.
Currently, the pictures are in a slideshow (bootstrap_carousel) and there is just an input type="text"
Is it a good start?
Any better suggestions?
Thank you very much!
