It was Brennig's. But I see that the project has been sucked up by Ashampoo. I'm sure they'll turn it to shit in no time, if not already.
i have a lot of pictures, but i spend 99% of my time using a quick image viewer (freeware irfanview), rather than inside one of the image browsing apps like acdsee.
now i know that acdsee has an image viewer, but im more interested in having a really super fast and convenient image viewer that shows images when i double click them from windows explorer.
With acdsee 7.0 I've tried excluding the root of each hard drive (and subfolders) from being thumbnailed but that doesn't work. You have to exclude the folders below the root or they disappear upon restart . In fact, being unable to switch the thumbnail/database thing off really is annoying.

But the problem with this--and it is a problem--is that in order to benefit from this feature, you have to give up some privacy. As a trade-off to the update checks, the idiots try forcing you to submit usage statistics to them on a regular basis.
