Denoise is not working or I'm doing something terribly wrong

Is there a files area or somewhere that I can post my image?
Denoise does almost nothing to my image regardless of the settings. I can see tiny little changes after the image update, but the noise is as bad or worse than the input image. While the image is very noisy, the difference between figure (a portrait) and noise is apparent.
How can I troubleshoot this?

Typically, you can attach an image to your post. The only exception I know of is if your account is new enough to still be on “probation”.

PS Don’t forget to clearly note which version of DeNoise you are working with.

What do I have to do in order to be allowed to post an image?
