Wd my cloud pictures resize over dlna

Is there any way to disable picture resizing or transcoding on the wd my cloud twonky dlna, i have good quality pictures on the nas server but over dlna they are resized to a lower resolution, I have read that via ssh (read the post iam attaching) on this folder /usr/local/twonkymedia-5/cgi-bin   there are 3 files: convert-jpeg.desc, jpeg-scale.desc and thumb-jpeg.desc, which area use by twonky for converting any image format to jpeg and scaling them and it says that renaming them to *.old, it will stop the conversion and scaling rules for images now, but on twonkymedia 7 i dondt see this file thumb-jpeg.desc

Any help on this matter will be appreciated.

Thanks

The aforementioned adjustment is not supported.

Have you tried rescanning the media files or changing the settings of the Twonky media server?

The following article shows how to access the server on the My Cloud.
