- Paperclip 4.0 requires a validation rule for file attachments
- Set this to accept common image types (jpg, png, gif)

This makes your code more portable, as you need bootstrap 3 to run it. On systems that have an older version installed, your app will see that bootstrap is already installed but then will hit errors when it runs.

This is the validation rule which checks that the file being uploaded has one of the standard image content-types, so that someone would be prevented from uploaded a pdf for example. You'd probably want to add additional validation rules, like on the max file size, for example.

This is just to test that the image upload was working. You'd probably want to display a thumbnail version of the image instead what this is doing, which is showing the original.
