Create gallery in frontend

 Hello. I added the custom field to the registration form, but It doesn´t work as it asks the user to set a lot of caracteristics and options.
Where can I find a tutorial where I can see how a user can add images or categories?

Thank you!

Sorry, I don´t know how to paste a capture here. I´ll try to explain.

When the user goes to Edit profile, he finds the diferent fields, and one of them is Showtime. Showtime field displays another different fields, such a:

- Titlle
- A menu with: Add images, Delete All Images, Options
- The gallery where the pictures are added to (which by the way, it doesn´t work, I get a message saying "Upload failed".
- Then OPTIONS
- Images
- Display
- Thumbnail Image Width *
- Thumbnail Image Height *
- Thumbnail Image Resize Method *
and so...

Thank you!
