Not aware of any solution that solves this as you describe anymore. OBEX seems to be a bit old, and not something we have any examples on or support for. That doesn't necessarily mean it wont work, but you will have to implement it yourself.

I think that in the majority of the cases a separate app is needed to get this behavior.

The BLE image transfer demo is doing a file transfer in a partial way, so not in one go but in sections, and then the app updates the image in the viewer when it has received the entire jpeg file. So it is possible to use that basis for a different solution. But it does use an additional app.

Alternatives are maybe OTP(Object transfer profile) since BLE does not have a FTP solution that lets you send files back and forth.

The nRF Connect app can receive a lot of data and save it in to a text file or something else, so that can also an option.

So that means it is only possible to transfer picture to e.g. an android device when there is a application available which is receiving the picture. So it is not possible to do something like OBEX where you not need a additional app, to receive the image. Correct?

If you are OK with sticking to a older SDK then the NordicPlayground example is the "latest and greatest" we have. If not then try looking at some of the NCS samples. The reply in this ticket https://devzone.nordicsemi.com/f/nordic-q-a/93875/nrf52-ble-image-transfer-demo-upgrade-to-nrf-connect-sdk/395850 shead some light on the project and its status.
