Backing paper stock image ideas

Gathered a few examples of generic stock images that would be seen as a representation of a photograph in photo frames, I understand the use of actual photos is important to represent what a photo would look like in context of the frame style. But personally i don't like the idea i like the idea of simple vector imaging and typography to create an original outcome as opposed to generic common outcomes commonly seen. 

I feel type only ones also present versatility as certificates and such documents can be simulated this way.
