Please appraise my domain: StockPicture.net

Yes, I understand your points about the .net domain and also about usage of proper English keyword "StockPhotos" instead of uncommon keyword "StockPicture".

In this context I would like to ask additional question again, but about these domains I own:

StockPhotos.sk (.sk is .tld of Slovak Republic)
StockPhotos.cz (.cz is .tld of Czech Republic)
StockPhotos.mx (.mx is .tld of Mexico)
StockPhotos.it (.it is .tld of Italy)
StockPhotos.li (.li is .tld of Lichtenstein)
StockPhotos.lu (.lu is .tld of Luxemburg)

How do you see possible 1.) current and 2.) future value of these domain names?

I am not willing to sell them. I am just curious about their possible value.
It is exact keyword "StockPhotos" match, but on .tld of countries where English is not primary language.
On the other side English language and thus also "StockPhotos" term is more and more used also in these countries so it is not unknown word collocation.

Thank you for your answer(s).
