How does one stop thumbnails for images?

One of the reasons I abandoned Synology's own media server was its dreadful generation of image thumbnails (I calculated 3 months to do them.). I don't want thumbnails - I know where my pictures are.
I have looked everywhere but I can't see how to turn off image thumbnail generation. (If it matters: I am feeding jpg to a Panasonic TX-L42D25B which is seen as an Unrecognised Device.)
I have a Synology DS111, so pretty puny horsepower.

You can disable thumbnail generation on serviio console.

You said
"You can disable thumbnail generation on serviio console."
but I cannot find where you can do it. The only options I can see are tabs for Video and Audio.
Can you point me where to disable thumbnail generation for Images?
Thanks.

For Images ?! Do you really want to remove thumbnails generation ?
EDIT : In fact, I don't know how disable thumbnails generation for IMAGES ...

Yes, Images. Why would I want them? This is something the Synology developers don't understand. I am quite happy with the jpg's names and the containing directory's name. Neither MediaTomb nor Twonky generate them by default as far as I can see (but they have their drawbacks, that's why I'm looking at Serviio).

If I have ~40,000 jpgs it takes forever to generate thumbnails, probably longer than my attention span (lifetime?).

You cannot disable image thumbnails generation at the moment

That is a shame as Serviio came out top in my evaluation on my Synology. Can I be rude and ask if "at the moment" means "I am thinking about it" or "in your dreams Bob"? If not-thumbnailing might come in less than the time it takes to thumbnail, then I can live with Twonky for images and Serviio otherwise "at the moment" (!).
Thanks

I haven't thought about if unless you mentioned it. You can create a ticket but it might be a while before I get to it.

I too would really appreciate a way to disable thumbnail generation on photos. It totally kills the NAS. Is there a way to edit a config file or something as a temporary fix?

BTW: where are the thumbnails stored?
