My Valued Images
My QualityImages

Please see my user page on Wikipedia - I am highly active there.

My favourite images taken by me are at User:Piotrus/Image gallery (but I haven't updated this with many newer pics...). The oldest images uploaded by me are at User:Piotrus/Image gallery/old. Topic galleries are at User:Piotrus/Topic galleries (this does not contain some old pre-commonist galleries and some small hard-to-categorize photo series). Automated Commonist uploads and some hard-to-categorize stuff is at User:Piotrus/gallery. Photos of myself are at User:Piotrus/Photos of Piotrus.

If I forget to tag an image I uploaded that I made, feel free to tag it with dual license - GFDL and cc-by-sa-2.5,2.0,1.0. {{User:Piotrus/License}}

One of the things I'd like to to is to categorize images due to historical period they depict. I am now taking care of this category: Category:Polish-Lithuanian Commonwealth, a subactegory of Category:History of Poland, as well as of categories of cities I live in (Category:Katowice, Category:Pittsburgh).

Policy pages I was involved in creation of: Commons:Licensing/Justifications, Commons:Fan art, Commons:Guidelines for class projects
