, which means you should consider other operations, such as create, update and delete.  This will help determine which of the above operations to offer - e.g.

Do you ever create a banner without an image?

If you do, you should offer both resources.  But you could still embed the image resource if it exists, to save the second GET request.
If you don't, then there's no problem just offering the banner resource - from the client's perspective, they should never consider the banner without an image

How often do you update the image without updating other properties of the banner?

If the answer is frequently, then it could be helpful to offer the image resource - but again, you could still embed the resource to save the second GET request

Suggestion on your Data Structure
You mention that the image might be used for other types of images, but that a banner could only have one image.  If that is the case, I'd suggest reversing the direction of the relationship, e.g.:
table Banner                    table Images
________________________        ______________________
| id       | Int       |        | id        | Int    |
| title    | VARCHAR   |        | filename  | VARCHAR|
| image_id | Int       |        |___________|________|

 Q:

Parse: Facebook login not creating new PFUser

I've been trying to integrate Facebook login and Parse, so that a new PFUser is created upon logging in. I have created a Facebook login button, and when I press it the standard Facebook login/asking for permissions screen appears. When I accept the login I am redirected back to the initial screen, and the log shows that the user has cancelled the Facebook login. When I check my data on the Parse website, there are no PFUsers.
As far as I can tell I have followed the exact instructions laid out by Parse (https://parse.com/docs/ios/guide#users) and Facebook.(https://developers.facebook.com/docs/ios/getting-started).

 Do you always create a banner without an image? 

 If you suffice, you should offer both resources.   But you could however embed the image resource if it exist, to save the second GET request. 
 If you don't, then there's no trouble just offering the banner resource - from the client's perspective, they should never consider the banner without an persona 

 How often do you update the image without updating early properties of the banner? 

 If the solution is frequently, then it could be helpful to offer the effigy resource - but again, you could still implant the resource to save the second GET request 

 Suggestion on your Data Structure 
 You mention that the picture might be used for other types of images, but that a banner could merely have one image.   If that is the case, I'd suggest reversing the direction of the relationship, e.g.:
