I’ve made a couple of mockup frame setups for presenting pictures in a similar way.
There are 2 files: 70×50 cm (Landscape) and 50×70 cm (Portrait).
Each of the files have 6 different frame widths (12, 15, 20, 25, 30 and 40mm) and includes options with and without a passepartout. If you have a favourite frame width I would recommend you to delete the unneeded layers to minimise the file size.
The files should be drag and drop compatible, so just drag your image into the placeholder frame and it should be cropped accordingly.
I hope you find it useful.
